Application ID: 11509420

Base Claim:
1. A method comprising: concatenating one or more electrical digital signals representing binary expressions of individual ones of characters of a first character expression in a first binary string, said characters of said first character expression representing a first numerical value of a first numerical expression represented by a concatenation of said individual ones of characters of said first character expression according to a non-binary position-value notation; concatenating one or more electrical digital signals representing binary expressions of individual ones of characters of a second character expression in a second binary string, said characters of said second character expression representing a second numerical value of a second numerical expression represented by a concatenation of said individual ones of characters of said second character expression according to said non-binary position-value notation; and determining a relationship between said first and second numerical values based, at least in part, on said first and second binary strings.

Claim 17:
17. The method of claim 1 , wherein said determining said relationship further comprises: determining signs of differences between corresponding portions of said first and second binary strings; weighting said signs of differences based, at least in part, on a significance of said corresponding portions of said first and second binary strings; and determining said relationship based, at least in part, on a sum of the weighted signs of differences.
