> +#define HUMAN_SIZE_LONGEST 64 (5) The integer constant expression ((sizeof (uint64_t) * 8 + 2) / 3 + 1) would be more frugal (but we might not care). If we take the number of three-bit groups in the word, and divide that by three -- rounded up --, we get the number of necessary octal digits. The number of decimal digits needed never exceeds the number of octal digits needed, so this is safe. Add one character for the NUL terminator.)
