log1p()

Example

Compute the natural logarithm of 1 plus x for various values of x.

System.out.println(Math.log1p(6));
System.out.println(Math.log1p(Math.E));
System.out.println(Math.log1p(2));
System.out.println(Math.log1p(1));
System.out.println(Math.log1p(0));
System.out.println(Math.log1p(-1));

Definition and Usage

The log1p() method in Java returns the natural logarithm of 1 + x for any given value of x.

This logarithm uses the base e, where e is approximately 2.718282, and is represented by the constant Math.E in Java.

Syntax

public static double log1p(double number)
