20080270495 | INSERT/EXTRACT BIASED EXPONENT OF DECIMAL FLOATING POINT DATA - A decimal floating point finite number in a decimal floating point format is composed from the number in a different format. A decimal floating point format includes fields to hold information relating to the sign, exponent and significand of the decimal floating point finite number. Other decimal floating point data, including infinities and NaNs (not a number), are also composed. Decimal floating point data are also decomposed from the decimal floating point format to a different format. For composition and decomposition, one or more instructions may be employed, including an insert biased exponent or extract biased exponent instruction. | 10-30-2008 |
