Angle.atan2 constructor
Create an angle by computing the arc tangent from y / x
.
This uses the atan2()
function, therefore there are two
separate parameters for the nominator and the denominator.
The result is an angle in ]-180°;180°]
.
Sample values:
y=0, x=0
=> 0°y=0, x=1
=> 0°y=1, x=0
=> 90°y=0, x=-1
=> 180°y=-1, x=0
=> -90°
Implementation
Angle.atan2(final double y, final double x) : _storage = math.atan2(y, x);
