StrictMath getExponent() Method In Java
- The getExponent(double num) is an inbuilt method of StrictMath class which is used to get the unbiased exponent to be used in the representation of a given double argument. It gives rise to two special results:
- The result will be Double.MAX_EXPONENT + 1 when the given argument is NaN or infinite
- The result is Double.MIN_EXPONENT – 1 when the argument is zero.
Syntax :
public static int getExponent(double num)
Parameters: The method accepts one parameter num of double type whose unbiased exponent is supposed to be found.
Return Value: The method returns the unbiased exponent which used in the representation of the given double argument.
Examples:
Input: num = 75.45 Output: 6.0 Input: num = 0.0 Output: -1023.0

Output:Exponent of 93.5 = 6.0
- The getExponent(float num) is an inbuilt method of StrictMath class which is used to get an unbiased exponent, to be used in the representation of a given float argument. It gives rise to two special results:
- The result will be Float.MAX_EXPONENT + 1 when the given argument is NaN or infinite
- The result is Float.MIN_EXPONENT – 1 when the argument is zero.
Syntax :
public static int getExponent(float num)
Parameters: This method accepts one parameter num which is of float type whose unbiased exponent we want to find.
Return Value: The method returns the unbiased exponent which used in the representation of the given float argument.
Examples:
Input: num = 10254.25f Output: 13.0 Input: num = 10.25f Output: 3.0
