Method

ATan


Description

Returns the arctangent of the value specified. The arctangent is the angle whose tangent is value.

Usage

result = ATan(value)

Part

Type

Description

result

Double

The arctangent of value.

value

Double

The value you want the arctangent of.

Notes

The ATan function returns the angle (in radians) of the number passed to it. To express the arctangent in degrees, multiply the result by 180/PI.

Sample code

This example uses the ATan function to return the arc tangent of a number.

Var d As Double
Const Pi = 3.14159265358979323846264338327950
d = ATan(1) ' returns 0.785398 (PI/4 radians)
d = ATan(1) * 180 / Pi ' returns 45

Compatibility
