Abstract
The present invention provides a method, data processing system and computer program for comparing first and second floating point numbers involving providing a hierarchy of tests arranged to identify from said first and second floating point numbers whether said one or more exception conditions exist. Each test is arranged to generate a hit signal if that test predicts that one or more exception conditions exist. If the executed test generates a hit signal and is not the final test in the hierarchy, the method branches to the next test in the hierarchy, executes that test and returns to the step of determining whether the executed test has generated a hit signal. If the executed test generates a hit signal and is the final test in the hierarchy, an exception signal is generated indicating the presence of one or more exception conditions.
