How can I use randomize, random and randomrange in Delphi

In Delphi, you can use the Randomize function to initialize the random number generator, the Random function to generate a random floating-point value between 0 and 1, and the RandomRange function to generate a random integer within a given range.

Here’s an example of how to use these functions

uses
  System.SysUtils;

var
  R: Real;
  I: Integer;
begin
   //Initialize the random number generator with the current time
  Randomize;

   //Generate a random floating-point value between 0 and 1
  R := Random;
  ShowMessage(FloatToStr(R));

   //Generate a random integer between 1 and 10
  I := RandomRange(1, 10);
  ShowMessage(IntToStr(I));
end;

uses

System.SysUtils;

var

R: Real;

I: Integer;

begin

//Initialize the random number generator with the current time

Randomize;

//Generate a random floating-point value between 0 and 1

R := Random;

ShowMessage(FloatToStr(R));

//Generate a random integer between 1 and 10

I := RandomRange(1, 10);

ShowMessage(IntToStr(I));

end;

The Randomize function seeds the random number generator with a value that is based on the current time. This ensures that the random numbers generated will be different each time the program is run.

The Random function returns a random floating-point value between 0 and 1, while the RandomRange function returns a random integer within the specified range.

You can find more information about these functions and other ways to generate random numbers in Delphi in the Delphi documentation.
