SDL_fabs(3)

💖 SDL_fabs(3) — the "how big is this number tho" page 💖

okay so bestie, welcome to the SDL3 FUNCTIONS corner of the manual, where today's main character is SDL_fabs 🎀 she's tiny, she's iconic, she takes a number and gives you back its magnitude. no vibes, no sign, no negativity allowed (literally, the minus sign gets evicted) ✨

---

🌸 NAME 🌸

SDL_fabs — Compute the absolute value of x 💅

---

✨ SYNOPSIS ✨

#include <SDL3/SDL_stdinc.h>

double SDL_fabs(double x);

---

🦋 DESCRIPTION 🦋

okay so here's the vibe check on the numbers she'll accept and the numbers she'll hand back:

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

so like, she's chill with literally any double you throw at her, from negative infinity all the way to positive infinity, and she always gives you back something that's zero or bigger. no cap 🫶

This function operates on double-precision floating point values, so if you're rolling with single-precision floats instead, go use SDL_fabsf — she's got a whole separate sister for that, and they do NOT share shoes 👑

---

🍓 FUNCTION PARAMETERS 🍓

• x — the floating point value to use as the magnitude. yes queen, hand her the raw number, she'll strip the sign off it herself 💖

---

🌈 RETURN VALUE 🌈

Returns the absolute value of x. that's it, that's the whole payoff, and honestly? she ate. 🔥

---

👑 THREAD SAFETY 👑

It is safe to call this function from any thread. go wild, launch a thousand threads, she does not care, she's built different 💅

---

⭐ AVAILABILITY ⭐

This function is available since SDL 3.2.0. so if you're on something older than that... bestie. it's giving ancient. upgrade era 🙈

---

💜 SEE ALSO 💜

• SDL_fabsf(3) — the single-precision little sister, same energy, smaller floats 🧚

---

ngl this one's a genuine no-thoughts-just-vibes function: number goes in, positive number comes out. the way that math is just that simple sometimes 🎀

---

okay that's the whole page, mwah 💋 this lil slice of the docs ships with Simple Directmedia Layer as part of SDL 3.4.18 — thanks for reading, bestie, now go compute some magnitudes and slay ✨🦋💖
