Abstract
A circuit for receiving a plurality of signed operands which each represent an exponential value to a predetermined base and for selecting one of the operands which results in a maximum value is taught. The circuit has a rank ordered plurality of logic circuits which each receives a predetermined bit of each operand and provides an output bit of the maximum value. The output of the logic circuits is a transcoded output which is a translation value of the maximum value. A sign control circuit receives a sign bit of each signed operand and controls the operation of the logic circuits in response to the values of the input operands.
