function Random: Extended;
The random function generates random numbers. These can be floating-point numbers in the following range:
0 <= Number < 1.0
It can be used by calling as follows. This call will generate a decimal random number value between 0 and 1.
x = Random();
If you want to get an integer value, define it as follows. Here it will return a random value between 0 and 100. After that, you can get values as you want.
x = Random() * 100;
Example
var
randomNumber,randomNumber2 : Integer;
{
randomNumber = Random();
randomNumber2 = Random() * 100;
ShowMessage(randomNumber);
ShowMessage(randomNumber2);
}
It assigns a different value with each execution. The output will not be the same.
To generate a random number where you can specify the start and end values, visit the GenerateRandom page.
Output:
0,197623564163223
52,8056032489985
