SDL_round(3)

💖 SDL_round(3) 💖

okay bestie, welcome to the SDL3 FUNCTIONS section of the manual, and today's main character is SDL_round — she's literally just here to round your numbers and look cute doing it ✨

---

🌸 NAME 🌸

SDL_round — round x to the nearest integer, no cap 🎀

---

✨ SYNOPSIS ✨

#include <SDL3/SDL_stdinc.h>

double SDL_round(double x);

like. that's the whole vibe. one include, one function, one double. slay 💅

---

🦋 DESCRIPTION 🦋

So here's the tea, bestie: SDL_round rounds x to the nearest integer. That's it, that's the job 🫶

But wait, there's a lil plot twist for the halfway girlies: values that land exactly halfway between two integers get rounded away from zero. So she's not doing that "round half to even" banker nonsense — she's picking a side and committing. main character energy fr fr 💀

Here's the domain and range, because we're thorough in this house:

• Domain: -INF <= x <= INF
• Range: -INF <= y <= INF, y integer

And a lil heads up so you don't text the wrong person: this function operates on double-precision floating point values. If you're working with single-precision floats, go hit up SDL_roundf instead. And if you want the result handed back to you as an actual integer type? That's SDL_lround's whole thing. iykyk 😌

---

🌈 FUNCTION PARAMETERS 🌈

• x — floating point value. just. a float. a lil guy. the number you want rounded 💜

---

⭐ RETURN VALUE ⭐

Returns the nearest integer to x. that's the whole delivery, no strings attached, no drama 🎁

---

🧚 THREAD SAFETY 🧚

It is safe to call this function from any thread. periodt. go wild, call her from everywhere at once, she does not care 💅✨

---

👑 AVAILABILITY 👑

This function is available since SDL 3.2.0. so if you're on anything older... bestie. it's giving ancient. update 💀
