Rem Operator
Divides two numbers and returns only the remainder.
Syntax
Operator construct
expression_1 Rem expression_2
Function construct
Rem ( expression_1, expression_2 )
Parts
expression_1- A numeric expression.
expression_2- A numeric expression.
Instructions
The result is the remainder after expression_1 is divided by expression_2.
For example, the expression 42 Rem 5 gives a result of 2.
The result has the same sign as expression_2.
Compared to Rem, the result of the related operator Mod gets the sign of its first number.
But it can be easy to select the correct operator for the given conditions.
The letter “M” is nearer to the number that gives the result its sign.
Data types
TODO
Trying to divide by zero
If expression_2 is zero, the result of Rem is related to the data type of its expressions and which construct you use:
- An integer division causes an exception
DivisionByZeroException, if you use the operator construct. - A floating-point division returns
Real64.NaN, if you use the operator construct. - If you use the function construct, it returns
expression_1for all possible data types.

Program Example
#Debug.PrintLine "42 Rem 5 = " & 42 Rem 5
#Debug.PrintLine "-42 Rem 5 = " & -42 Rem 5
#Debug.PrintLine "42 Rem -5 = " & 42 Rem -5
#Debug.PrintLine "-42 Rem -5 = " & -42 Rem -5
42 Rem 5 = 2 -42 Rem 5 = 2 42 Rem -5 = -2 -42 Rem -5 = -2 |
