✨ SDL_modf ✨

okay bestie, welcome to the SDL_modf(3) page from the SDL3 FUNCTIONS collection 💖 this one is short, sweet, and honestly kind of iconic — it splits a number in two like it's dividing the aux cord between you and your bestie 🎀

🌸 NAME 🌸

SDL_modf — split x into integer and fractional parts. it's giving "cut the pizza, keep both slices" 🍓

🦋 SYNOPSIS 🦋

#include <SDL3/SDL_stdinc.h>

double SDL_modf(double x, double *y);

like. one include. one function call. that's it. no cap ✨

💅 DESCRIPTION 💅

okay so here's the tea: this function operates on double-precision floating point values 💜 so if you're rolling with doubles, you're in the right place.

but if you're a float girlie (single-precision), you do NOT belong here — you want SDL_modff instead. don't mix them up, i'm literally begging 🙈

🌈 FUNCTION PARAMETERS 🌈

  • x — floating point value. the number that's about to get split, main character energy fr 💫
  • y — output pointer to store the integer part of x. bestie this is a pointer, so hand it an address, not a value 👑

⭐ RETURN VALUE ⭐

Returns the fractional part of x 🎀

so like, x goes in, and the function hands you back the fractional half while dropping the integer half into wherever *y points. teamwork. iconic. periodt 💅

🧚 THREAD SAFETY 🧚

It is safe to call this function from any thread 🫶 no locks, no drama, no situationship with your mutex. call it from literally anywhere. slay 🔥

👑 AVAILABILITY 👑

This function is available since SDL 3.2.0 ⭐ so if you're on anything older... yeah. update bestie, it's 3.2.0+, no excuses 🌸

💖 SEE ALSO 💖

iykyk — go read those next, they're all part of the same friend group 🌈

lowkey reminder: y is a pointer and it's an output parameter, so make sure it points somewhere real before you call this. undefined behaviour is not the vibe, bestie 💀
