The following information applies to DriveWorks 15 SP2 only.
The function ExtractNumber previously returned the extracted number as a string value.
This incurred an additional function (Number) to be used to convert the value to a number, when being used in a comparison argument.
From DriveWorks 15 SP2 the ExtractNumber function returns all extracted numbers as numbers.
This means no further conversion is required when using the value.
Any existing rules that do convert the value returned from the ExtractNumber function will still operate as expected.
