Description of formula:

Calculates the arctangent of a specified number. Arctangent is the angle, whose tangent is equal to value passed as a parameter, e.g.

atan(1) = π/4, because tan(π/4) = 1

The returned value is given in radians, in range from –π/2 to π/2.

Syntax:

atan(number)

atan(number)

Parameters:

number

(type: Number) The tangent of the angle

Returned type:

Number

Examples:

=atan(-1)

=atan(Section1.A1)

=atan(A)

=atan(B3)

=atan(-1)

=atan(Section1.A1)

=atan(A)

=atan(B3)

Remarks:

If you want to get value in degrees, multiply the result by 180/pi().
