Consistancy in using typedefs

[MusicMonkey5555]

This is the only place I noticed it but found it a bit odd. Not really a bug, but think it should be changed none the less. In Engine\source\platform\types.h

getMin for both float and double (line 221 & 227) use the words float and double rather than the typecast F32 and F64 where as all the others use them.

Simple enough change. Once I start getting pull requests working I can add this if someone else doesn't before me.

Appears fixed now :).
