[edit] Common mathematical functions
The header math.h provides standard C library mathematical functions such as fabs, sqrt, and sin.
[edit] Floating-point environment
The header fenv.h defines flags and functions related to exceptional floating-point state, such as overflow and division by zero.
[edit] Pseudo-random number generation
The header stdlib.h also includes C-style random number generation via srand and rand.
[edit] Complex number arithmetic
The header complex.h povides types and functions about complex numbers.
[edit] Type-generic math
The header tgmath.h provides some macros for a function which names XXX:
- real function:
-  float variant XXXf
-  double variant XXX
-  long double variant XXXl
 
-  float variant 
- complex function:
-  float variant cXXXf
-  double variant cXXX
-  long double variant cXXXl
 
-  float variant
