Description

Multiplies pi by a specified number.

Syntax

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)

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))
