Let us make Sage reals and rationals more friendly
to formatting commands that expect Python floats.
For example, with a Python float one can do
```
sage: a = 1.25r
sage: "{:0.3f}".format(a)
'1.25…

### Problem
Rationals don't support very big/very small numbers and sometimes produce incorrect result
### Desired Behavior
Work correctly ._.
### How to Reproduce
1. Do `Rational…

Using poly_factor on polynomial with rational coefficients returns unexpected result.
Eg :
```
>> R, x = PolynomialRing(QQ, 'x')
(Univariate Polynomial Ring in x over Rationals, x)
>> poly_…

jsown reads numbers as rationals, which is somewhat annoying since we usually want floats for performance, and also allows for DOS by putting huge exponents in the data.
Need to watch performance i…

The FormulaManagers for Integers, and possibly Rationals, are incomplete in CVC4. They do not support multiplication for example. However, CVC4 supports these operations.
We need to analyze which ope…

I'm using `build_function` to convert a Symbolics expression to a C function. The symbolic expression includes rationals, for example `1//2`. These are converted verbatim to C, where they become comme…

Should we use aliases for standard types? E.g.,
```julia
const RealTime = Double
const NoteValue = Rational{Int}
const MidiTicks = Int
```
This could improve self-documentation and readability…

Really short term (and enough to close this issue): two examples, since the directory name has an "s" at the end.
Long term: all of them (or, if something better comes up, as many but better).

## Description
@morganthomas I want an audit section on the choice of `Rational` over `Double`. Please type some notes about your thinking here, let me worry about audit language.
