atan2()

Syntax

atan2(y, x)

Returns

Number

Description

Returns the angle in degrees whose tangent is the quotient of two specified numbers (y/x). Unlike atan(), this function evaluates the signs of both arguments to determine the correct quadrant of the resulting angle.

Arguments

  • y (Number): The y-coordinate (vertical component).
  • x (Number): The x-coordinate (horizontal component).

Examples

  • atan2(1, 1) results in 45.
  • atan2(1, -1) results in 135.
  • atan2(-1, -1) results in -135.
  • atan2(VerticalG, GForce) can be used to determine the angle of the total G-force vector.
