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);
}
