Function Atan2

math/all.go:55–57

Atan2 returns the arc tangent of y/x, using the signs of the two to determine the quadrant of the return value. Special cases are (in order): Atan2(y, NaN) = NaN Atan2(NaN, x) = NaN Atan2(+0, x>=0) = +0 Atan2(-0, x>=0) = -0 Atan2(+0, x<=-0) = +Pi Atan2(-0, x<=-0) = -Pi Atan2(y>0, 0) = +Pi/2

(y, x float32)

//	Atan2(+Inf, x) = +Pi/2
//	Atan2(-Inf, x) = -Pi/2
func Atan2(y, x float32) float32 {
	return engomath.Atan2(y, x)
}

// Atanh returns the inverse hyperbolic tangent of x.
