# Synopsis

PDX_MSGT mth_GetAngle2DPoint(long option, double *pnt, double *angle, long *angle_status)

# Purpose

Get the angle between X axis and the line through a point and the origin

# Description

The angle between the X axis and the line going through a point and the origin will be computed. It can be in radians or degrees per the option chosen and is within [0, 360) degrees. An error would be issued if the point is at the origin.

Though only 2D data will be used, for convenience, the input can be of any dimension.

# Input

## option

Options (not used)

## pnt

# Output

## angle

The angle [0, MTH_2_PI)

## angle_status

### MTH_ANGLE_CALCULATED

, Calculated an angle.

### MTH_ANGLE_POINT_ORIGIN

, Point to close to origin to calculate an angle.
