SDL_lround(3)

💫 SDL_lround 💫

ok so bestie, welcome to the SDL_lround page from the SDL3 FUNCTIONS lineup 🎀 she rounds a double to the nearest long and honestly? she ate.

---

✨ NAME ✨

SDL_lround — Round x to the nearest integer representable as a long 💅

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_stdinc.h>

long SDL_lround(double x);

like yes that's it, that's the whole vibe 🦋

---

💖 DESCRIPTION 💖

So what she does: rounds x to the nearest integer. And the lil plot twist — values that are halfway between integers get rounded away from zero. no indecision, no "idk maybe", she picks a side and commits 🔥

Domain: -INF <= x <= INF

Range: MIN_LONG <= y <= MAX_LONG

ngl this one is the double-precision floating point girlie ✨ so if you're rolling with single-precision floats, you want SDL_lroundf instead. And if what you actually want back is a floating-point type rather than a long, then SDL_round is your bestie. iykyk 💫
