NAME¶

SDL_tan - Compute the tangent of x.

SYNOPSIS¶

#include <SDL3/SDL_stdinc.h>

double SDL_tan(double x);

DESCRIPTION¶

Domain: -INF <= x <= INF

Range: -INF <= y <= INF

This function operates on double-precision floating point values, use SDL_tanf for single-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 tangent of x.

THREAD SAFETY¶
