Diff

Function Name:

Diff

Description:

Takes 2 numbers and returns the difference between them expressed as a positive value. For example, if you wanted to see the age difference between a person and their first spouse (in years), you could use this expression:

=Diff(Year(%INDI.BIRT.DATE%),Year(%INDI.~SPOU>BIRT.DATE%))

If, on the other hand, you wanted to subtract the latter from the former so that you get a negative value if the spouse is born later than the first person, you could use this:

=Calc(Year(%INDI.BIRT.DATE%) -Year(%IND.~SPOU.BIRT.DATE%))
