getExponent() float in Java

getExponent(): This method is available in the Math class of Java.

Syntax:

int java.lang.Math.getExponent(float f)

This method takes one argument of type float as its parameter. This method returns the unbiased exponent used in the representation of a float.

Special cases:

1. If the argument is NaN or infinite, then the result is Float.MAX_EXPONENT + 1.

2. If the argument is zero or sub normal, then the result is Float.MIN_EXPONENT -1.

Parameters: One parameter is required for this method.

f: a float value

Returns: the unbiased exponent of the argument.

For Example:

Math.getExponent(8.5)  = > It returns 3.

Approach

Java

public class GetExponentFloat {
    public static void main(String[] args) {

        float x = (float) 8.5;
        System.out.println(Math.getExponent(x));

    }
}

Output:

3
