Pi( )
Returns the value of Pi accurate to 15 decimal places
(3.14159265358979). Note that without applying a

mask, Pi( )
will only actually display 11 decimal places. The following example
uses Pi( )
to calculate the circumference of a
circle with a radius of 12 inches:
<cfset r=12> <cfset Circumference = 2*Pi( )*r> <cfoutput> The circumference of a circle with a radius of 12 inches is #Circumference# inches. </cfoutput>
