Abstract
An interpolation circuit included in a computer system may receive an operand that includes a plurality of bits occupying respective ones of a plurality of ordered bit positions, and generate multiple conditionally-negated values of respective portions of the operand starting at corresponding bit positions. The interpolation circuit may combine the operand and the plurality of conditionally-negated values to generate an approximation of a result of an arithmetic operation performed on the operand.
