Core Function Random

Random( <minValue>, <maxValue>, <flag> )

Description

Get a random number from the defined area.

Parameters

minValue

A number, or a variable containing a number.

$var = 5;

maxValue

A number, or a variable containing a number.

$var2 = 33;

flag

Type of random to generate.

0 = Generate an integer (Int32) random number and store return value as a Double
1 = Generate an integer (Int32) random number and store return value as an Int32
2 = Generate an integer (Int64) random number and store return value as an Int64
3 = Generate an integer (Int64) random number and store return value as a Double

Default: Generate a random double number (min: 0, max: 1) and store return value as a Double

Return Value

Success: Returns a random number.

Failure: Does not return a random number (if an expression is not properly defined).

Remarks

Warning:

The lower bound is inclusive and the upper bound is exclusive.

That means that Random() will return the lower number, but it is guaranteed to never return the upper one.

This means if you wish to generate a random number from 1 to 3 you must request from 1 to 4.

The same goes if you wish to generate a random number from 0.1 to 0.3 you must request from 0.1 to 0.4.

Example

$var = 5; // first expression
$var2 = 33; // second expression
$ran = Random($var, $var2); // function in variable
printf($ran); // print a random number from $ran
