NAME
====
Math::FractionalPart provides several routines to operate with the fractional parts of a number. All routines also operate on complex numbers.
SYNOPSIS
========
```raku
use Math::FractionalPart :afrac;
say (afrac -3.2); # Output <<0.2>>
say (frac -3.2); # Output <<-0.2>>
```
DESCRIPTION
===========
There are three different algebraic functions that operate on numbers and return their fractional parts. They all return the same result when operating on non-negative numbers, but all three return different results when operating on negative numbers. See the [References](#References) for more details. Note that Ref. 2 shows *frac* operating in the *complex plane* as `frac(x + i y) = frac(x) + i frac(y)`.
The following table shows the routines that have been implemented in this module.
