Mod
Mod
| Mod ( number1 ; number2 ) -> Function result | ||||||||
| Parameter | Type | Description | ||||||
| number1 | Longint |
|
Number to divide | |||||
| number2 | Longint |
|
Number to divide by | |||||
| Function result | Real |
|
Returns the remainder | |||||
The Mod command returns the remainder of the Integer division of number1 by number2.
Notes:
- Mod accepts Integer, Long Integer, and Real expressions. However, if number1 or number2 are real numbers, the numbers are first rounded and then Mod is calculated.
- Be careful when using Mod with real numbers of a large size (above 2^31) since, in this case, its operation may reach the limits of the calculation capacities of standard processors.
You can also use the % operator to calculate the remainder (see Numeric Operators).
WARNING: The % operator returns valid results with Integer and Long Integer expressions. To calculate the modulo of real values, you must use the Mod command.
The following example illustrates how the Mod function works with different arguments. Each line assigns a number to the vlResult variable. The comments describe the results:
vlResult:=Mod(3;2) ` vlResult gets 1
vlResult:=Mod(4;2) ` vlResult gets 0
vlResult:=Mod(3.5;2) ` vlResult gets 0
