Numerics - cppreference.com

From cppreference.com

The C numerics library includes common mathematical functions and types, as well as support for random number generation.

Common mathematical functions

The header

<math.h>

provides

standard C library mathematical functions

such as

fabs

sqrt

, and

sin

Floating-point environment

The header

<fenv.h>

defines

flags and functions related to exceptional floating-point state

, such as overflow and division by zero.

Pseudo-random number generation

The header

<stdlib.h>

also includes C-style random number generation via

srand

and

rand

Complex number arithmetic

The header

<complex.h>

provides types and functions to work with

complex numbers

Type-generic math

The header

<tgmath.h>

provides some macros for a function which names XXX:

real function:

float variant XXXf

double variant XXX

longdouble variant XXXl

complex function:

float variant cXXXf

double variant cXXX

longdouble variant cXXXl

Bit manipulation

(since C23)

The header

<stdbit.h>

provides macros and functions to work with the

byte ordering

and

byte and bit representation

of C objects.

Checked integer arithmetic (since C23)

Provides some

type-generic macros

for checked integer arithmetic:

(C23)

checked addition operation on two integers
(type-generic function macro)
