Modulus '//', '//='

Modulus can be used in both variable and integer constant expressions, but not in floating-point constant expressions. Modulus divides one value by another and returns the 32-bit integer remainder. Example:

X := Y // 4 

If Y started out as 5 then Y // 4 equals 1, meaning the division of 5 by 4 results in a real number whose fractional component equals ¼, or .25.

Modulus has an assignment form, //=, that uses the variable to its left as both the first operand and the result destination. For example,

X //= 20     'Short form of X := X // 20 

Here, the value of X is divided by 20 and the 32-bit integer remainder is stored back in X. The assignment form of Modulus may also be used within expressions for intermediate results; see Intermediate Assignments.
