BE CAREFUL: BREAKING CHANGES !!! ##### Most notable changes 1. Full support for **ES modules**. Support for tree-shaking out of the box. Load all functions: ```js import * as math from 'mathjs' ``` Use a few functions: ```js import { add, multiply } from 'mathjs' ``` Load all functions with custom configuration: ```js import { create, all } from 'mathjs' const config = { number: 'BigNumber' } const math = create(all, config) ``` Load a few functions with custom configuration: ```js import { create, addDependencies, multiplyDependencies } from 'mathjs' const config = { number: 'BigNumber' } const { add, multiply } = create({ addDependencies, multiplyDependencies }, config) ``` 2. Support for **lightweight, number-only** implementations of all functions: import { add, multiply } from 'mathjs/number' 3. New **dependency injection** solution used under the hood. ##### Breaking changes - Node 6 is no longer supported. - Functions `config` and `import` are not available anymore in the global context: ```js // v5 import * as mathjs from 'mathjs' mathjs.config(...) // error in v6.0.0 mathjs.import(...) // error in v6.0.0 ``` Instead, create your own mathjs instance and pass config and imports there: ```js // v6 import { create, all } from 'mathjs' const config = { number: 'BigNumber' } const mathjs = create(all, config) mathjs.import(...) ``` - Renamed function `typeof` to `typeOf`, `var` to `variance`, and `eval` to `evaluate`. (the old function names are reserved keywords which can not be used as a variable name). - Deprecated the `Matrix.storage` function. Use `math.matrix` instead to create a matrix. - Deprecated function `math.expression.parse`, use `math.parse` instead. Was used before for example to customize supported characters by replacing `math.parse.isAlpha`. - Moved all classes like `math.type.Unit` and `math.expression.Parser` to `math.Unit` and `math.Parser` respectively. - Fixed [#​1428](https://togithub.com/josdejong/mathjs/issues/1428): transform iterating over replaced nodes. New behavior is that it stops iterating when a node is replaced. - Dropped support for renaming factory functions when importing them. - Dropped fake BigNumber support of function `erf`. - Removed all index.js files used to load specific functions instead of all, like: // v5 // ... set up empty instance of mathjs, then load a set of functions: math.import(require('mathjs/lib/function/arithmetic')) Individual functions are now loaded simply like: ```js // v6 import { add, multiply } from 'mathjs' ``` To set a specific configuration on the functions: ```js // v6 import { create, addDependencies, multiplyDependencies } from 'mathjs' const config = { number: 'BigNumber' } const math = create({ addDependencies, multiplyDependencies }, config) ``` See example `advanced/custom_loading.js`. - Updated the values of all physical units to their latest official values. See [#​1529](https://togithub.com/josdejong/mathjs/issues/1529). Thanks [@​ericman314](https://togithub.com/ericman314). ##### Non breaking changes - Implemented units `t`, `tonne`, `bel`, `decibel`, `dB`, and prefixes for `candela`. Thanks [@​mcvladthegoat](https://togithub.com/mcvladthegoat). - Fixed `epsilon` setting being applied globally to Complex numbers. - Fix `math.simplify('add(2, 3)')` throwing an error. - Fix [#​1530](https://togithub.com/josdejong/mathjs/issues/1530): number formatting first applied `lowerExp` and `upperExp` and after that rounded the value instead of the other way around. - Fix [#​1473](https://togithub.com/josdejong/mathjs/issues/1473): remove `'use strict'` in every file, not needed anymore. ### [`v5.10.3`](https://togithub.com/josdejong/mathjs/blob/HEAD/HISTORY.md#​2019-05-18-version-5103) [Compare Source](https://togithub.com/josdejong/mathjs/compare/v5.10.2...v5.10.3) - Fixed dependency `del` being a dependency instead of devDependency. ### [`v5.10.2`](https://togithub.com/josdejong/mathjs/blob/HEAD/HISTORY.md#​2019-05-18-version-5102) [Compare Source](https://togithub.com/josdejong/mathjs/compare/v5.10.1...v5.10.2) - Fix [#​1515](https://togithub.com/josdejong/mathjs/issues/1515), [#​1516](https://togithub.com/josdejong/mathjs/issues/1516), [#​1517](https://togithub.com/josdejong/mathjs/issues/1517): broken package due to a naming conflict in the build folder of a util file `typeOf.js` and `typeof.js`.

BE CAREFUL: BREAKING CHANGES !!! Breaking changes (see also [#​682](https://togithub.com/josdejong/mathjs/issues/682)): - **New expression compiler** The compiler of the expression parser is replaced with one that doesn't use `eval` internally. See [#​1019](https://togithub.com/josdejong/mathjs/issues/1019). This means: - a slightly improved performance on most browsers. - less risk of security exploits. - the code of the new compiler is easier to understand, maintain, and debug. Breaking change here: When using custom nodes in the expression parser, the syntax of `_compile` has changed. This is an undocumented feature though. - **Parsed expressions** - The class `ConstantNode` is changed such that it just holds a value instead of holding a stringified value and it's type. `ConstantNode(valueStr, valueType`) is now `ConstantNode(value)` Stringification uses `math.format`, which may result in differently formatted numeric output. - The constants `true`, `false`, `null`, `undefined`, `NaN`, `Infinity`, and `uninitialized` are now parsed as ConstantNodes instead of SymbolNodes in the expression parser. See [#​833](https://togithub.com/josdejong/mathjs/issues/833). - **Implicit multiplication** - Changed the behavior of implicit multiplication to have higher precedence than explicit multiplication and division, except in a number of specific cases. This gives a more natural behavior for implicit multiplications. For example `24h / 6h` now returns `4`, whilst `1/2 kg` evaluates to `0.5 kg`. Thanks [@​ericman314](https://togithub.com/ericman314). See: [#​792](https://togithub.com/josdejong/mathjs/issues/792). Detailed documentation: https://github.com/josdejong/mathjs/blob/v4/docs/expressions/syntax.md#implicit-multiplication. - Immediately invoking a function returned by a function like `partialAdd(2)(3)` is no longer supported, instead these expressions are evaluated as an implicit multiplication `partialAdd(2) * (3)`. See [#​1035](https://togithub.com/josdejong/mathjs/issues/1035). - **String formatting** - In function `math.format`, the options `{exponential: {lower: number, upper: number}}` (where `lower` and `upper` are values) are replaced with `{lowerExp: number, upperExp: number}` (where `lowerExp` and `upperExp` are exponents). See [#​676](https://togithub.com/josdejong/mathjs/issues/676). For example: ```js math.format(2000, {exponential: {lower: 1e-2, upper: 1e2}}) ``` is now: ```js math.format(2000, {lowerExp: -2, upperExp: 2}) ``` - In function `math.format`, the option `notation: 'fixed'` no longer rounds to zero digits when no precision is specified: it leaves the digits as is. See [#​676](https://togithub.com/josdejong/mathjs/issues/676). - **String comparison** Changed the behavior of relational functions (`compare`, `equal`, `equalScalar`, `larger`, `largerEq`, `smaller`, `smallerEq`, `unequal`) to compare strings by their numeric value they contain instead of alphabetically. This also impacts functions `deepEqual`, `sort`, `min`, `max`, `median`, and `partitionSelect`. Use `compareNatural` if you need to sort an array with text. See [#​680](https://togithub.com/josdejong/mathjs/issues/680). - **Angle units** Changed `rad`, `deg`, and `grad` to have short prefixes, and introduced `radian`, `degree`, and `gradian` and their plurals having long prefixes. See [#​749](https://togithub.com/josdejong/mathjs/issues/749). - **Null** - `null` is no longer implicitly casted to a number `0`, so input like `math.add(2, null)` is no longer supported. See [#​830](https://togithub.com/josdejong/mathjs/issues/830), [#​353](https://togithub.com/josdejong/mathjs/issues/353). - Dropped constant `uninitialized`, which was used to initialize leave new entries undefined when resizing a matrix is removed. Use `undefined` instead to indicate entries that are not explicitly set. See [#​833](https://togithub.com/josdejong/mathjs/issues/833). - **New typed-function library** - The `typed-function` library used to check the input types of functions is completely rewritten and doesn't use `eval` under the hood anymore. This means a reduced security risk, and easier to debug code. The API is the same, but error messages may differ a bit. Performance is comparable but may differ in specific use cases and browsers. Non breaking changes: - Thanks to the new expression compiler and `typed-function` implementation, mathjs doesn't use JavaScript's `eval` anymore under the hood. This allows using mathjs in environments with security restrictions. See [#​401](https://togithub.com/josdejong/mathjs/issues/401). - Implemented additional methods `isUnary()` and `isBinary()` on `OperatorNode`. See [#​1025](https://togithub.com/josdejong/mathjs/issues/1025). - Improved error messages for statistical functions. - Upgraded devDependencies. - Fixed [#​1014](https://togithub.com/josdejong/mathjs/issues/1014): `derivative` silently dropping additional arguments from operator nodes with more than two arguments. #### 2018-02-07, version 3.20.2 - Upgraded to `typed-function@0.10.7` (bug-fix release). - Fixed option `implicit` not being copied from an `OperatorNode` when applying function `map`. Thanks [@​HarrySarson](https://togithub.com/HarrySarson). - Fixed [#​995](https://togithub.com/josdejong/mathjs/issues/995): spaces and underscores not property being escaped in `toTex()`. Thanks [@​FSMaxB](https://togithub.com/FSMaxB). #### 2018-01-17, version 3.20.1 - Fixed [#​1018](https://togithub.com/josdejong/mathjs/issues/1018): `simplifyCore` failing in some cases with parentheses. Thanks [@​firepick1](https://togithub.com/firepick1). #### 2018-01-14, version 3.20.0 - Implement support for 3 or more arguments for operators `+` and `*` in `derivative`.

Thanks [@​joelhoover](https://togithub.com/joelhoover). - Fixed `simplify` throwing an error in some cases when simplifying unknown functions, for example `simplify('f(4)')`. Thanks [@​joelhoover](https://togithub.com/joelhoover). - Fixed [#​1013](https://togithub.com/josdejong/mathjs/issues/1013): `simplify` wrongly simplifing some expressions containing unary minus, like `0 - -x`.
