💖 SDL_log10f(3) — SDL3 FUNCTIONS 💖

okay bestie, pull up a chair, we're doing logarithms today 🌸 and honestly? she's giving main character energy. this is SDL_log10f, and she computes the base-10 logarithm of x. periodt.

✨ SYNOPSIS ✨

#include <SDL3/SDL_stdinc.h>

float SDL_log10f(float x);

like, that's it. one include, one function, one float. no cap. 🫶

🦋 DESCRIPTION 🦋

okay so here's the vibe check on what she accepts and what she gives back:

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

and listen. it is an error for x to be less than or equal to 0. not "a little oopsie", an error. so don't do that. 🙈

this function operates on single-precision floating point values, so if you're on that double-precision grind, use SDL_log10 instead. iykyk. ✨

and here's the part that's lowkey important: 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, don't be out here assuming the exact same digits on every box, bestie. she's consistent in spirit, not necessarily in the last bit. 💅

🎀 FUNCTION PARAMETERS 🎀

  • x — floating point value. Must be greater than 0.

that's the whole list. one parameter. iconic behaviour honestly. 👑

⭐ RETURN VALUE ⭐

Returns the logarithm of x. slay. that's the whole thing. 🔥

🌈 THREAD SAFETY 🌈

It is safe to call this function from any thread.

so yes, you can call her from literally anywhere. she doesn't get weird about it. no drama. 💜

🌸 AVAILABILITY 🌸

This function is available since SDL 3.2.0.

so if you're on something older than that... girl. upgrade. 😭

💫 SEE ALSO 💫

⚠️ reminder bestie: x must be greater than 0. less than or equal to zero is an error, and the domain tops out at INF. that's the whole boundary, don't test it. 🚫
