Java.lang.StrictMath.getExponent() Method

Description

The java.lang.StrictMath.getExponent(float f) method returns the unbiased exponent used in the representation of a float.It include some cases:

• If the argument is NaN or infinite, then the result is Float.MAX_EXPONENT + 1.
• If the argument is zero or subnormal, then the result is Float.MIN_EXPONENT -1.

Declaration

Following is the declaration for java.lang.StrictMath.getExponent() method

public static int getExponent(float f)

Parameters

• f -- This is the float value.

Return Value

This method returns the unbiased exponent used in the representation of a float.

Exception

• NA

Example

The following example shows the usage of java.lang.StrictMath.getExponent() method.

package com.tutorialspoint;

import java.lang.*;

public class StrictMathDemo {

  public static void main(String[] args) {
  
    float f1 = 32 , f2 = 1024;

    // returns the unbiased exponent used in the representation of a float
    double exponentValue = StrictMath.getExponent(f1);
    System.out.println("Exponent value of " + f1 + " = " + exponentValue);

    exponentValue = StrictMath.getExponent(f2);
    System.out.println("Exponent value of " + f2 + " = " + exponentValue);
  }
}

Let us compile and run the above program, this will produce the following result:

Exponent value of 32.0 = 5.0
Exponent value of 1024.0 = 10.0
