1521     # The next step is to compare the exponents, but since each mantissa is an
1558     # mantissa. Life is a lot easier if we first make both exponents
1618     # mantissa with zeros (shift left) until it has the same length as the
1619     # longer mantissa.
1675     # so make mantissa equal-length by padding with zero (shift left)
1774     # e.g., 12e+3 becomes 12000e+0 and we can easily increment the mantissa.
