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
| 
					 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18  | 
						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.
