Returns Pi, the perimeter-to-diameter-ratio of a circle
- Syntax
-
- PI () -> nPi
- Returns
-
- <nPi> the math constant Pi with maximum precision available
- Description
-
- The function PI() can be used if the constant Pi is needed with maximum precision. One of the most known interpretations of this number is the constant perimeter-to-diameter-ratio of circles.
Examples
// the diameter of a circle-like swimming pool is 3.4 meters, how
// long is the perimeter ?
? str(PI()*3.4,5,3)+" meters" --> 10.681 meters
