how write pi in delphi

To write the value of pi in Delphi, you can use the predefined constant Pi. Here is an example:

  myPi: Double;
  myPi := Pi;
  // Use the value of myPi as needed

In this code snippet, we declare a variable myPi of type Double and assign the value of Pi to it. The Pi constant represents the mathematical constant π, which is approximately equal to 3.14159265358979323846.

You can then use the value of myPi in your Delphi program as needed.
