The minus operator (-) works the expected way for integers/dates.
nTen = 16 - 6
nYesterday = Today() - 1
Note that the - operator is not defined for the boolean and string data type.
Additionally, the - operator can be used as a unary operator, where it simply returns the negative of the value of the variable it operates on.
nProfit = -nDeficit
nDiscount = -35
