The java.lang.Math.getExponent() is a built-in math function which returns the unbiased exponent used in the representation of a float.
- 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.
Syntax:
public static int getExponent(float val)
Parameter:
val - a float value
Returns:
The method returns the unbiased exponent of the argument.
Example: To show working of java.lang.Math.getExponent() function
import java.lang.Math;
class Gfg {
public static void main(String args[])
{
float x = 7689 .1f;
float y = - 794 .99f;
System.out.println(Math.getExponent(x));
System.out.println(Math.getExponent(y));
System.out.println(Math.getExponent( 0 ));
}
}
