Pi

Description

Multiplies pi by a specified number.

Syntax

Pi ( n )

Pi ( n )

Argument	Description
n	The number you want to multiply by pi (3.14159265358979323…)

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)

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)

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))

1 2	real degree = 45.0, cosine cosine = Cos(degree * (Pi(2)/360))
