atan()
Syntax
(
number
).atan
atan (
number
)
Description
Math function; calculates the arctangent, which is the angle whose tangent is a specified number. The result is a value in radians between pi/2 and +pi/2.
Example
This statement displays the arctangent of 1:
(1).atan
The result, to four decimal places, is 0.7854, or approximately pi/4.
Note that most trigonometric functions use radians, so you may want to convert from degrees to radians.
Example
This handler lets you convert between degrees and radians:
on DegreesToRads degreeValue return degreeValue * PI/180 end
The handler displays the conversion of 30 degrees to radians in the Message window:
put DegreesToRads(30) -- 0.5236
