💖 SDL_sin(3) 💖

okay so bestie, you're in the SDL3 FUNCTIONS section of the manual, and today's main character is... sine 🦋✨

✨ NAME ✨

SDL_sin — compute the sine of x. that's it, that's the whole vibe 💅

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_stdinc.h>

double SDL_sin(double x);

🎀 DESCRIPTION 🎀

okay so, the domain situation: -INF <= x <= INF — like, anything goes in there, no cap.

and the range: -1 <= y <= 1 — it always comes back with a number between -1 and 1, periodt. 👑

this one is double-precision floating point, okay? if you want single-precision floats, you want SDL_sinf instead. don't mix them up bestie, i'm serious 🫶

⚠️ and here's the tea: 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 go around assuming it's bit-identical everywhere, because it is not. 💀

🧚 FUNCTION PARAMETERS 🧚

  • x — floating point value, in radians. yes, radians, not degrees. i know. we've all been there 🙈

⭐ RETURN VALUE ⭐

Returns sine of x. slay. ✨

🌈 THREAD SAFETY 🌈

It is safe to call this function from any thread. no drama, no locks, just vibes. 💜

💫 AVAILABILITY 💫

This function is available since SDL 3.2.0. if your SDL is older than that, it's giving... nothing, honestly. 😭

👑 SEE ALSO 👑

and that's the whole page, bestie!! this one came to you from the Simple Directmedia Layer girlies, running SDL 3.4.18 — so go forth, compute your sines, stay in your range, and remember: radians only 💅✨🎀🦋🌸💖
