In FORTRAN, the last digit "C" is rounded up to "D" in order to maintain the highest possible accuracy: Console x = 3FF0CCCCCCCCCCCD (Hex representation of 1.05D0) Even after rounding, the result is not perfectly accurate. There is some error after the least significant digit, which we can see by removing the first digit.

This is because the values is sign * 2^exp * mantissa. The exp is adjusted so the mantissa starts 1. There are also sub-normal numbers which don't do this, but this only applies to very small numbers.

WebWords beginning with the third word in the array contain the mantissa. Mantissa words are ﬂoating point whole numbers between 0 and one less than the radix.
