The java.lang.StrictMath.expm1() is an inbuilt method in Java which is used to return the exponential e^num -1 for a given value of num. The method gives rise to four different cases:
- The method returns NaN when the given argument is NaN.
- The result is positive infinity when the argument is positive infinity.
- The result is negative infinity when the argument is negative infinity.
- For 0 the methods return 0 with the same sign as the argument.
public static double expm1(double num)
Parameters: This method accepts one parameter num of double type and refers to the value on which the exponential operation is to be performed.
Return Value: The method will return the result of enum – 1 operation.
Input: num = (1.0/0.0) Output: Infinity Input: 32.2 Output: 9.644557735961714E13
