====== Cross platform format string ======

<code c>
#include <stdint.h>    // for uint64_t
#include <inttypes.h>  // for PRIu64

size_t my_variable;
printf("%" PRIu64 "\n", (uint64_t)my_variable);
</code>

====== Float padding ======

The field //width// includes the decimal point and the fractional portion (and the sign, if it's negative).


===== Padding negative numbers =====
Flags:
    * <code>-</code> Left-justify the given field width (see Width below). Right justification is the default.
    * <code>+</code> Forces a "+" sign to precede a number. Has no effect on negative numbers.
    * <code>(space)</code> One blank space is inserted before a positive number, while negative numbers are unaffected. This is useful for making positive and negative numbers vertically align in a visual stacked list.
