* Windows MSVC < 2012 'round' function updatematkuki2016-06-171-5/+11
| | | | Microsoft Visual C++ compilers prior to 2012 do not implement the 'round', 'roundl' or 'roundf' functions. This change is fixes this. Tested it with MSVC 2010.

* Implemented function to split floating point numbers at the decimal place ↵A. S. Budden2016-05-311-0/+25

* Modification to implementation of round() such that it returns a float and ↵A. S. Budden2016-05-311-25/+67
| | | | | | accepts a places argument (fixes #3473). This also involved moving some functions around to get the hierarchy correct and the documentation for frexp was modified such that it was clear that it can return a float in either the range [-1, -0.5] or [0.5, 1].

* | Fix exponentiation operation to avoid overflow.Reimer Behrends2015-08-141-1/+3
| | | | | | | | | | | | The exponentation implementation unnecessarily multiplied the result with itself at the end if the exponent was an even number. This led to overflow if result*result > high(int).

| | | | | | I still used generics, but made them choose from `float32` or `float64`. I can rewrite in separate, explicit procs if is wanted
| * Conversion between radians and degrees.Fixes #2881apense2015-06-241-0/+17
| | | | | | provides a new constant for conversion (not public, but that can be changed if it's wanted). the functions are pretty simple, honestly. top-level comment so documentation for each function could remain. Fixes #2881

* Discarded randomize for windowsapense2015-06-111-6/+9
| | | It actually doesn't use it because `rand_s` doesn't.
* Updated random functionsapense2015-06-111-4/+12
| | | For Windows, `rand_s` has been available since Windows XP (see https://msdn.microsoft.com/en-us/library/sxtz2fa8.aspx). It gives a better quality random number in a larger range (the max is actually `0xffffffff`).
