A method includes receiving an input data at a floating point arithmetic operating unit, wherein the floating point operating unit is configured to perform a floating point arithmetic operation on the input data. The method includes determining whether the received input data is a qnan (quiet not-a-number) or whether the received input data is an snan (signaling not-a-number) prior to performing the floating point arithmetic operation. The method also includes converting a value of the received input data to a modified value prior to performing the floating point arithmetic operation if the received input data is either qnan or snan, wherein the converting eliminates special handling associated with the floating point arithmetic operation on the input data being either qnan or snan.
