Java Math toDegrees()

Syntax of Math toDegrees()in Java

The syntax of the toDegrees() method is:

Parameters of Math toDegrees() in Java

The toDegrees() method takes only one parameter.

• angle: The angle in radians that needs to be changed to degrees.

Return Value of Math toDegrees() in Java

• Returns the angle measured in degrees
• Return type is double

Exceptions of Math toDegrees() in Java

Math.toDegrees() does NOT throw any exception.

Example

Note: To convert an angle in radians to degrees we simply multiply it with 180/π.

In this example we are going to see how to use/call Math.toDegrees() method in java.

Output:

Explanation:

• In above code we have simply converted angle in radian to angle in degrees using Math.toDegrees() method of the Math class.
• As we know, 3.14, which is roughly equal to π, is very close to 180 degrees.

What is Math toDegrees() in Java?

An angle measured in radians is converted to a roughly comparable angle measured in degrees using the Math.toDegrees() method.

• This method will return NaN if the argument is NaN
• This method will return zero with the same sign as the argument if the argument is zero.
• This method will return Infinity with the same sign as the input if the argument is Infinity.

More Examples

Example 1

In this example, we are going to see how to convert radians to degrees using toDegrees() method in Java:

Output:

Explanation:

• In the above Example, we have converted the angle in radians to degrees using toDegrees() method in Java.
• We have initialized x and y as 1.5708 and -0.0, and converted them into degrees.

Example 2

In this example, we are going to use toDegrees() method in java with NaN.

Output:

Explanation:

• As we have discussed above that toDegrees() will return NaN when a NaN is passed as argument.

Note: Square of a negative number is NaN in Java.

Example-3

In this example, we are going to see how to use Math.toDegrees() in java with Infinity.

Output:

Explanation:

• As we discussed above that this method will return Infinity with the same sign as the input if the argument is Infinity.
• So in the above code Infinity is printed when POSITIVE_INFINITY is passed and -Infinity is printed when NEGATIVE_INFINITY is passed.
