    A robust integer math code does not use C, it is a PITA
    otherwise. Period. SCNR.

    Instead of emulating the multiplication, why not check against overflows
    BEFORE "*= 10"? You need to check after the addition as well.

    C math sucks. It's almost as ugly as assembler, but it doesn't let you
    test the overflow flag which would TRIVIALLY report an overflow.
