✨ SDL_fmod ✨

ok so bestie, welcome to the SDL_fmod page from the SDL3 functions manual 💖 this is the one that gives you the floating-point remainder of x / y, and we're gonna go through it together, no stress.

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_stdinc.h>

double SDL_fmod(double x, double y);

💅 DESCRIPTION 💅

So basically it divides x by y, and returns the remainder. That's it. That's the whole vibe. 🫶

The domain (aka the stuff you're allowed to feed it) is:

  • -INF <= x <= INF
  • -INF <= y <= INF
  • y != 0

And the range (aka what you can get back) is:

  • -y <= z <= y

Lowkey important: this function operates on double-precision floating point values. If you're working with single-precision floats, you want SDL_fmodf instead — don't come for me, that's just how it is. 😌

🎀 FUNCTION PARAMETERS 🎀

  • x — the numerator. the top of the fraction, the main character of the division. 👑
  • y — the denominator. Must not be 0. fr fr, zero is not the move here. 💀

⭐ RETURN VALUE ⭐

Returns the remainder of x / y. slay. 💖

🦋 THREAD SAFETY 🦋

It is safe to call this function from any thread. go off, multitask, thread it up, it's fine. ✨

🌈 AVAILABILITY 🌈

This function is available since SDL 3.2.0. not ancient, not brand new — just right. 🧚

👑 SEE ALSO 👑

reminder bestie: keep y away from 0 or the whole thing falls apart. it's giving undefined behaviour energy and we do NOT want that. 😭

and that's the page!! mwah 💋 this came from the Simple Directmedia Layer crew — SDL 3.4.18, dated with the SDL_fmod(3) footer vibe — love them, follow them, they ate. 🫶✨💅
