Fortran mantissa
WebThe programmer has had little controlover the way in which data can be input and the layout of printed results. Input and output statements can contain information on how input … The significand (also mantissa or coefficient, sometimes also argument, or ambiguously fraction or characteristic ) is part of a number in scientific notation or in floating-point representation, consisting of its significant digits. Depending on the interpretation of the exponent, the significand may represent an integer or a fraction.

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.

WebMar 16, 2024 · (Hex) in the mantissa. 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.
