  # Modf
  
  This module Provides a Raku version of routine 'modf' as used in other languages.
  
  Note the `modf` routine is **not** currently available in the Raku core, but there is an open Rakudo Pull Request (#4434) to add it. Thus it is likely to be in the core by the 2021.07 release of Rakudo.
  
  # SYNOPSIS
  
  ```
  use Modf;
  say modf(3.2);            # OUTPUT: «3 0.2␤»
  say modf(-3.2);           # OUTPUT: «-3 -0.2␤»
  
  ```
  
  # DESCRIPTION
  
  ## modf
  
  ```
  sub modf($x is copy, $places? --> List) is export(:modf) {...}
  
  ```
  
  The c routine (currently not available in the *Raku* core) is similar to those in other languages including *C*, *C++*, *Python*, and *Haskell*. It coerces its input into a base 10 number and returns the integral and fractional parts in a list as shown below. (Note the `modf` routine has been submitted as a PR for the Raku core and may be part of the language soon.)
  
  ```
  say modf(3.24);  # OUTPUT: «3 0.24␤»
  say modf(-2.7);  # OUTPUT: «-2 -0.7␤»
  say modf(10);    # OUTPUT: «10 0␤»
  say modf(0x10);  # OUTPUT: «16 0␤»
  say modf(-0o10); # OUTPUT: «-8 0␤»
  
  ```
  
  Note the sign of the input value is applied to both parts, unless the part is zero. As expected, the fractional part of an integer will be zero. If desired, the user may use the optional parameter `$places` (a positive integer) to specify the precision to be shown in the fractional part.
  
  ```
  say modf(1.23456);    # OUTPUT: «1 0.23456␤»
  say modf(1.23456, 3); # OUTPUT: «1 0.235␤»
  
  ```
