💖 SDL_log10 — it's giving math, bestie 💖

okay so you found yourself in the SDL3 FUNCTIONS section of the manual, staring at SDL_log10(3), and honestly? slay. let's get into it.

✨ NAME ✨

SDL_log10 — Compute the base-10 logarithm of x.

like. the log base ten. the one your calculator has a button for. that one. 🎀

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_stdinc.h>

double SDL_log10(double x);

🦋 DESCRIPTION 🦋

Domain: 0 < x <= INF

Range: -INF <= y <= INF

bestie. listen. it is an error for x to be less than or equal to 0. not "a little weird", not "eh it'll be fine" — an actual error. do not pass it a zero. do not pass it a negative. i am begging. 💀

This function operates on double-precision floating point values, so if you're out here working with single-precision floats, use SDL_log10f instead. she's the float version. different girl, same vibe. ✨

Also, real talk: this function may use a different approximation across different versions, platforms and configurations. which means it can literally return a different value given the same input on different machines or operating systems, or if SDL gets updated. so don't go comparing outputs across boxes and having a meltdown. it's not a bug, it's just how she moves. 🫶

👑 FUNCTION PARAMETERS 👑

  • x — floating point value. Must be greater than 0. that's it. that's the whole requirement. but it IS a requirement. 😭

⭐ RETURN VALUE ⭐

Returns the logarithm of x. iconic behaviour, no notes. 💅

🌈 THREAD SAFETY 🌈

It is safe to call this function from any thread. go forth. spawn threads. she can handle it. main character energy fr fr. 💜

🧚 AVAILABILITY 🧚

This function is available since SDL 3.2.0. so if you're on something older, that's a you problem, bestie. upgrade. 🍓

🔥 SEE ALSO 🔥

iykyk. go read those next. ✨

and that's the whole page, no cap. every option, every bound, every vibe — preserved. periodt. 💖
