Fixed-point arithmetic instructions

The fixed-point arithmetic instructions treat the contents of registers as 32-bit signed integers.

The fixed-point arithmetic instructions treat the contents of registers as 32-bit signed integers. Several subtract mnemonics are provided as extended mnemonics of addition mnemonics. See Extended mnemonics of condition register logical instructions for information on these extended mnemonics.

There are differences between POWER® family and PowerPC® for all of the fixed-point divide instructions and for some of the fixed-point multiply instructions. To assemble a program that will run on both architectures, the milicode routines for division and multiplication should be used. See Using Milicode Routines for information on the available milicode routines.
