Use hexadecimal floating point literals instead of decimal

[angelsl]

Would appreciate if someone took a look at this. Quite trivial change. Thanks.

Would appreciate it if someone reviewed this.

Visual C++ does not support hexadecimal floating point literals.
Since all of these are actually integers they should work without the ".0" and ".0f".

I thought I tested it on MSVC.

I'll check again.
