pow10(3)

✨ pow10(3) ✨

okay bestie, welcome to the pow10 page, a certified member of the Linux Library Functions Manual family 💖 this one is short but it's giving "came back from the dead only to get ghosted" energy, and honestly we're obsessed 😭

🌸 NAME 🌸

pow10, pow10f, pow10l — base-10 power functions, no cap 💅

🎀 LIBRARY 🎀

Math library (libm, -lm) 🧮✨

psst — if you link this without -lm, the linker is gonna act brand new. just saying 🫶

🦋 SYNOPSIS 🦋

#define _GNU_SOURCE         /* See feature_test_macros(7) */
#include <math.h>

double pow10(double x);
float pow10f(float x);
long double pow10l(long double x);

like yes boo, you have to define _GNU_SOURCE before you pull in <math.h> — that macro is the little backstage pass that unlocks these bad boys 👑

💜 DESCRIPTION 💜

So what do they even do? These functions return the value of 10 raised to the power x. That's it. That's the whole thing. ten to the x. iconic behavior honestly 🌈

Note well, bestie, and i mean it: these functions perform exactly the same task as the functions described in exp10(3), with one difference — those latter functions are now standardized in TS 18661-4:2015. So like… use those ones instead of the ones on this page. no shade to pow10, but exp10 is the main character now 💅
