Abstract
An apparatus for determining the correct value to be assigned to the 'sticky-bit' (S) position as a consequence of an arithmetic floating point multiply, divide or square root operation. The apparatus measures the number of trailing zeroes in the operand registers, performs a sum or difference calculation of these values, and compares the result with a third value to determine the sticky-bit value.
