2.5.4.51 IntersectY

  • Article

The IntersectY function calculates the y-coordinate of the point where two lines intersect. Each line is defined by a point on the line and an angle.

ABNF:

 IntersectY = val val val val val val " INTERSECTY():128"

Required Arguments:

Name: X1

Type: vDouble

An argument that specifies the x-coordinate of the point defining the first line.

Name: Y1

Type: vDouble

An argument that specifies the y-coordinate of the point defining the first line.

Name: Angle1

Type: vDouble

An argument that specifies the angle of the first line relative to the positive x-axis.

Name: X2

Type: vDouble

An argument that specifies the x-coordinate of the point defining the second line.

Name: Y2

Type: vDouble

An argument that specifies the y-coordinate of the point defining the second line.

Name: Angle2

Type: vDouble

An argument that specifies the angle of the second line relative to the positive x-axis.

Return Value:

Type: vNum, PtgErr

This function returns a vNum containing the y-coordinate of the point where two lines intersect. If any of the arguments X1, Y1, X2, Y2 is a vUnitType, the unit of the return value is equal to the unit of the first of those arguments that is a vUnitType. If none of those arguments is a vUnitType, the function returns a PtgNum. If Angle1 equals Angle2, the function returns a PtgErr with an error code of #DIV/0.
