The div Operator

The div operator stands for integer division. The operands must be integer

and its result is integer. The result of

A div B

is the integer you get when you divide A by B and throw away any remainder.

For example,

7 div 2

is the integer 3.

-7 div 2

is the integer -3.

The mod Operator

The mod operator stands for the mathematical ``modulo'' operation. Its

operands must both be integer. The general form of the operation is

A mod B

where A and B are expressions. The value of B must be positive.

The result of the mod operation is always non-negative, and is equal to A

modulo B. If A is non-negative, this value will be equal to

A - ( (A div B) * B )

In other words, it is the non-negative remainder that is left after A is

divided by B.

modulo modulo (moj'-l`, mod'y-l`) noun

An arithmetic operation whose result is the remainder of a division

operation. For example, 17 modulo 3 = 2 because 17 divided by 3 yields a

remainder of 2. Modulo operations are used in programming.
