Calculate the arc tangent of angle n / m.
n - the value (converted to a double) to apply this function to.
m - the value (converted to a double) to apply this function to.
A double scalar.
$y = 30; $x = 60; $value = atan2 ($y, $x); println("atan2 of 30/60 is : $value");
atan2 of 30/60 is : 0.4636476090008061
