Defined in <SDL3/SDL_stdinc.h>
double SDL_ceil(double x);| double | x | floating point value. |
(double) Returns the ceiling of x.
The ceiling of x is the smallest integer y
such that y > x, i.e x rounded up to the
nearest integer.
Domain: -INF <= x <= INF
Range: -INF <= y <= INF, y integer
This function operates on double-precision floating point values, use SDL_ceilf for single-precision floats.
It is safe to call this function from any thread.
This function is available since SDL 3.2.0.
