Mod (number1; number2) Number

Parameter | Type | Description | |

number1 | Number | Number to divide | |

number2 | Number | Number to divide by | |

Function result | Number | Returns the remainder |

Description

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.

Example

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
