This function is for BASIC compatibility. It is not available in pure JavaScript projects.

Atn(number)

Atn returns the arctangent of a number in radians. The required parameter, number, is any numeric expression.

To convert degrees to radians, multiply degrees by π/180. To convert radians to degrees, multiply radians by 180/π.

Rem Atn Example
'Atn calculates the arctangent of a number

Dim Pi
Pi = Atn(1) * 4
Print "The value of pi is " & Pi

The value of pi is 3.141592653589793
