f9a659f7ab Windows MSVC < 2012 'round' function update 
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.

46a2993917 Implemented function to split floating point numbers at the decimal place (equivalent to C's modf function). Fixes #4195. 2016-05-31 13:26:41 +01:00

0cc7c9a13c Modification to implementation of round() such that it returns a float and 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].

22789a8275 Fix exponentiation operation to avoid overflow. 
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).
