Use Java's Math.log1p() function to calculate the logarithm with base 1
The calculation formula of the Math.log1p() function is: ln(1 x), which is the logarithm with e as the base. It should be noted that when the value of x is close to 0, the calculation results of the Math.log1p() function will be more accurate.
Code example of using the Math.log1p() function to calculate the logarithm of base 1
The following is a code example of using the Math.log1p() function to calculate the logarithm of base 1 Number code example:
public class Log1pExample { public static void main(String[] args) { double x = 10.0; double log1pResult = Math.log1p(x); double logResult = log1pResult / Math.log(1.0); System.out.println("以1为底的对数结果为:" + logResult); } }
In the above code, we define a variable x with a value of 10.0. Then use the Math.log1p() function to calculate the base e logarithm of x and save it in the log1pResult variable. Next, we divide log1pResult by Math.log(1.0), which is the logarithm to the base e, to calculate the logarithm to the base 1 and save it in the logResult variable. Finally, we output the result as the base 1 logarithm.
Run the above code, the output result is:
The logarithm result with base 1 is: 2.3025850929940455
