# atan2

##### Description:

Function atan2 calculates the arctangent from the coordinates of a point.

Parameters and mixed up in places. If you call a function with parameters and (i.e., ), the function will return the arctangent from the point. x y 0.0 1.0 atan2(0.0, 1.0)(1.0, 0.0) |

##### Parameters:

(Float:X, Float:Y)

float | X | The X-coordinate of the point at which you want to find the arctangent. |

float | Y | The Y-coordinate of the point at which you want to find the arctangent. |

}

##### Return Values:

Arctangent from a point (the angle between the positive part of the x-axis and the straight line drawn from), in degrees. (x, y)(0, 0)(x, y)

##### Examples:

main() { atan2(0.0, 1.0) = pi / 2 = 90° new Float: result = atan2(1.0, 0.0); // parameters are mixed up (see note above) printf("%.4f", result); // Conclusion: 89.9999 }
