22. An apparatus comprising: means, comprising one or more processors, for concatenating 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; means, comprising said one or more processors, for concatenating 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 a non-binary position-value notation; and means, comprising said one or more processors, for determining a relationship between said first and second numerical values based, at least in part, on said first and second binary strings.
38. The apparatus of claim 22 , wherein said means for determining said relationship further comprises: means for determining signs of differences between corresponding portions of said first and second binary strings; means for 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 means for determining said relationship based, at least in part, on a sum of the weighted signs of differences.
