StrictMath.log1p(): This method is available in java.lang.StrictMath class of Java.

Syntax:

double java.lang.StrictMath.log1p(double x)

This method takes one argument of type double as its parameter. This method returns the natural logarithm of the sum of the argument and 1.

Note:

2. If the argument is positive infinity, then the result is positive infinity.

3. If the argument is negative, then the result is negative infinity.
