Integer Comparator (nI)

The Integer Comparator matches specifically on integers using the logic describe above. It accepts the parameters listed in the following table.

Table 7 nI Comparison Function Parameters


Parameter	Description
switch	Specifies whether a relative distance calculation or a direct string comparison is used. Specify “y” to use a relative distance calculation; specify “n” to use a string comparison.
range	The greatest difference between two integers at which the values could still be considered a possible match. When the difference between two numbers is greater than the relative distance, the numbers are considered a non-match (the weight becomes zero when the actual difference is the relative distance plus one).
