scan_double(3)

💖 scan_double(3) 💖

okay bestie, so we're in the Library Functions Manual, section 3, and the star of today's episode is scan_double — the little function that takes a floating point number written out in decimal ASCII and turns it into an actual double. no cap. 🦋

✨ NAME ✨

scan_double — parse a floating point number in decimal ASCII representation 💅

✨ SYNTAX ✨

#include <libowfat/scan.h>

size_t scan_double(const char *src,double *dest);

like, that's it. that's the whole vibe check. 🎀

✨ DESCRIPTION ✨

so here's the tea, bestie: scan_double parses a floating point number in decimal ASCII representation from src, and then it writes the result into dest. 📝✨

and the return value? it gives you back the number of bytes read from src. that's a size_t, so it's a count, it's giving "how much of this string did I actually consume". 🔥

✨ SEE ALSO ✨

• scan_xlong(3)
• scan_8long(3)

go read those too, iykyk 👑

and that's the whole page, periodt. this was scan_double(3), page of the Library Functions Manual section 3 — catch you in the next one, mwah 🫶💖🌸
