[Y_Less]

YIL the internal buffer for formatting floating point numbers is 64 characters:

PHP код:

    new str[256];
    format(str, sizeof (str), "%7.0100f", 4.4);
    print(str);
    printf("%7.0100f", 4.4); 


Should give numbers with 100 decimal places (mostly all zeros), but doesn't:

Код:

      4.40000009536743164062500000000000000000000000000000000000
      4.40000009536743164062500000000000000000000000000000000000

Edit:

I'll also expand on what Freaksken said (I didn't learn this today, I wrote the original code for it). You can combine variable width and precision, plus zero prefixes:

PHP код:

printf("%0*.*f", 3, 5, 4.4); // Gives "004.40000" 


Even better, this can totally replace "substring" code:

PHP код:

new str[] = "How are you?"
printf("%.3s", str[4]); // Gives "are"
