PI()
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
Compliance
PI() is compatible with CT3’s PI().
