NAME¶

SDL_cosf - Compute the cosine of x.

SYNOPSIS¶

#include <SDL3/SDL_stdinc.h>

float SDL_cosf(float x);

DESCRIPTION¶

Domain: -INF <= x <= INF

Range: -1 <= y <= 1

This function operates on single-precision floating point values, use SDL_cos for double-precision floats.

This function may use a different approximation across different versions, platforms and configurations. i.e, it can return a different value given the same input on different machines or operating systems, or if SDL is updated.

FUNCTION PARAMETERS¶

x

floating point value, in radians.

RETURN VALUE¶

Returns cosine of x.

THREAD SAFETY¶

It is safe to call this function from any thread.

AVAILABILITY¶

This function is available since SDL 3.2.0.
