Atn (Function)

Get the arc tangent of the expression specified.

Atn (<expression>)

Parameters

The expression that gets the arc tangent (integer type or double-precision type real numbers)

Return Value

Returns the value of the double-precision type number.

The content of the value is the arc tangent of the specified expression.This is returned within the radian range from -pi/2 to pi/2.

Description

In order to convert the value returned to degree notation, it is multiplied by 180/pi.

Specify either an integer type or double-precision type real number in the <Expression>.

Example
Get the arc tangent of Variable X#.

      X#=1

        XX#=Atn(X#)*180/3.141592

The result is as follows:(The fractional part is rounded up at the 4th place)

XX#=45.000
