SYNOPSIS
#include <SDL3/SDL_stdinc.h>
float SDL_scalbnf(float x, int n);
DESCRIPTION
Multiplies x by the nth power of the floating point radix (always 2).
Domain: -INF <= x <= INF,
n integer
Range: -INF <= y <= INF
This function operates on single-precision floating point values, use SDL_scalbn for double-precision floats.
FUNCTION PARAMETERS
- x
- floating point value to be scaled.
- n
- integer exponent.
RETURN VALUE
Returns x * 2^n.
THREAD SAFETY
It is safe to call this function from any thread.
AVAILABILITY
This function is available since SDL 3.2.0.
