# Angle

Angle-func

## Description

The angle(x, y) function returns the angle in radians measured between the positive X axis and the line joining the origin (0,0) with the point given by (**x**, **y**). The returned values range from 0 to . Note that angle(0, 0) returns a missing value because the result is undefined.

## Syntax

double angle(double x, double y)

## Parameter

**x**

- the X-coordinate

**y**

- the Y-coordinate

## Return

Returns the angle in radians measured between the positive X axis and the line joining the origin (0,0) with the point given by (**x**, **y**).

## Example

angle(1,1)=; //angle(1,1)=0.78539816339745
