Atn


Function Atn( numeric expression )


Returns the arctangent of numeric expression.


Syntax a = Atn( b )


Remarks

Atn returns the arctangent (inverse tangent) of an angle, numeric expression.


The angle returned will be expressed in degrees, in the range -90 to 90 degrees.

If you desire to use radians rather than degrees the result can be converted

to radians as follows:


To convert degrees to radians, multiply by (pi / 180)

To convert radians to degrees, multiply by (180/pi)

Example Script


NUMBER i = 45

NUMBER pi = 3.14159265359

PRINT "The arctangent of 45 degrees is "; ATN(TAN(i))

PRINT "Expressed in radians that is "; ATN(TAN(i)) * pi / 180


Script Output


The arctangent of 45 degrees is 88.7269699799433

Expressed in radians that is 1.54857776146828
