Abstract

A method for distinguishing an ordinary binary floating point number from an extraordinary binary floating point number is provided, the method including adding 1 to a B-bit biased exponent of a binary floating point number to produce a (B+1)-bit augmented exponent and sign-extending the augmented exponent to produce a (B+n)-bit transformed exponent. The method also includes testing the (B+n)-bit transformed exponent to determine if the (B+n)-bit transformed exponent is less than 2.
