What is Math.toDegrees() in Java?
toDegrees() is a static method that is used to convert a radian angle into approximately equivalent degree measures.
Note:
toDegrees()is an approximate conversion, so it may contain some errors. For example,sin(toRadians(90.0))cannot be exactly equal to 1.0.
Syntax
static double toDegrees(double radianAngle)
Parameters
radianAngle: An angle in radian measures.
Return value
toDegrees() returns the approximate angle value in degrees, which is of type double.
Code
In lines 11 and 13, we use Math.toDegrees() to convert argument values x and y in radian measure. We can also use this method to make our calculations easily, like in trigonometric functions.
