SDL_sqrtf(3)

✨ SDL_sqrtf ✨

ok bestie come CLOSE, we're doing math πŸ’… this is the SDL3 function that takes a number and hands you back its square root. iconic behavior honestly.


NAME

SDL_sqrtf β€” Compute the square root of x. πŸ“


SYNOPSIS

#include <SDL3/SDL_stdinc.h>

float SDL_sqrtf(float x);

DESCRIPTION

okay so here's the vibe check on the numbers you're allowed to feed it and the numbers it'll hand back:

  • Domain: 0 <= x <= INF
  • Range: 0 <= y <= INF

This one is the single-precision floating point girlie. if you need the double-precision version, that's a whole different function, go say hi to SDL_sqrt. 🫢

⚠️ heads up, no cap: this function may use a different approximation across different versions, platforms and configurations. like, it can literally return a different value given the same input on different machines or operating systems, or if SDL gets updated. so don't be out here assuming your result is gonna match your friend's result on a different setup, bestie 😭

FUNCTION PARAMETERS

  • x β€” floating point value. Must be greater than or equal to 0. that's the rule, that's the whole rule 🌸

RETURN VALUE

Returns the square root of x. that's it, that's the tea. ✨


THREAD SAFETY

It is safe to call this function from any thread. go wild, queen πŸ‘‘ call it from all of them if you want.


AVAILABILITY

This function is available since SDL 3.2.0. so if you're on something older... no she's not there yet πŸ™ˆ
