Description
Multiplies pi by a specified number.
Syntax
Pi ( n )
Return value
Double. Returns the result of multiplying n by pi if it succeeds and -1 if an error occurs. If n is null, Pi returns null.
Usage
Use Pi to convert angles to and from radians.
Examples
This statement returns pi:
Pi(1)
Both these statements return the area of a circle with the radius id_Rad, an instance variable of type double:
Pi(1) * id_Rad^2 Pi(id_Rad^2)
The following statements compute the cosine of a 45-degree angle:
real degree = 45.0, cosine cosine = Cos(degree * (Pi(2)/360))
