Where to find a description of all the math functions like floorf and others?

Question

math.h is not really a documentation. Is there something else that will describe these functions a but more in detail?

Answer 1

Since you indicated math.h I suppose you are using C++ so here's my currently booked marked reference

http://www.cplusplus.com/reference/clibrary/cmath/

Answer 2

Sure, for example you can look here

Answer 3

floorf() is a variant for the floor() function, accepting and returning float values instead of double.

The GNU Libc documentation is very helpful.

The iPhone documentation also has a man page about floor() functions.
