That's sensible; however, as sprintf(3) can theoretically[0] return -1,
it's safer to do an error check before using the value for computation.

        --zeurkous.

[0] This could actually happen if the format string is somehow invalid;
    in that case, the mistake won't trigger alarm bells but silently
    add a value of -1 if left unchecked. Eek.
