SDL_logf(3)

💖 SDL_logf(3) 💖

Okay so welcome to the SDL3 FUNCTIONS manual, bestie! This page is all about SDL_logf, and yes, she is a main character. 💅

✨ NAME ✨

SDL_logf — Compute the natural logarithm of x. That's the whole job, and she ate. 💖

🦋 SYNOPSIS 🦋

#include <SDL3/SDL_stdinc.h>

float SDL_logf(float x);

🌸 DESCRIPTION 🌸

Domain: 0 < x <= INF

Range: -INF <= y <= INF

It is an error for x to be less than or equal to 0. Not me side-eyeing invalid input — bestie, do not pass 0 or negatives, periodt. 🚫

This function operates on single-precision floating point values, use SDL_log for double-precision floats. So if you need the double-precision version, SDL_log is your girl. 😌

This function may use a different approximation across different versions, platforms and configurations. i.e, it can return a different value given the same input on different machines or operating systems, or if SDL is updated. So like, same input does not always mean same output everywhere — no cap, it's giving "depends on the vibe of your setup." 💀

💅 FUNCTION PARAMETERS 💅

• x — floating point value. Must be greater than 0. Strictly greater, bestie. 0 is not invited to the function. 🙅‍♀️

⭐ RETURN VALUE ⭐

Returns the natural logarithm of x. Slay. ✨

🧵 THREAD SAFETY 🧵

It is safe to call this function from any thread. Multithreaded icon behavior, honestly. 👑

📅 AVAILABILITY 📅

This function is available since SDL 3.2.0. If you're on something older, it's giving "not yet, babe." 😭
