1. A method comprising: identifying a scaled-integer value; determining a multiplier value by extracting first information from a first portion of a bitfield based on the scaled-integer value, wherein the first portion of the bitfield is configurable to include a first signed integer value; determining a scale value by extracting second information from a second portion of the bitfield based on the scaled-integer value, wherein the second portion of the bitfield is configurable to include a second signed integer value; and performing an arithmetic operation based on the multiplier value and the scale value.
