Header File

Function Parameters

x	floating point value, in radians

Return Value

Range: -1 <= y <= 1

This function operates on double-precision floating point values, use SDL_cosf 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.

Version

This function is available since SDL 3.0.0.
