How will be a number represented?Actually normalized floats have 53 bits of mantissa because the initial bit is always 1 hence not stored. There are 5 bits that are reserved in the giac::gen data for the type field, and the 48 remaining ones are for mantissa. The 5 missing bits are truncated to 0. |
