Support for binary operations ?

[Necmttn]

I would like to use fparse to create binary cases to execute like

x + y < z
x > y
x >= z
x + y + z = 10
etc 

is there a way to extend this functionality?

Those are boolean expressions, which do not evaluate in a number result. You can however register your own functions to achieve this, e.g. like this:

const fObj = new Formula('lessThan(x+y, z)'); // representing x + y < z
fObj.lessThan = (a, b) => a < b ? 1 : 0;
let result = fObj.evaluate({x: 1, y: 2, z: 4}); // => 1
