Natural Log Calculator

The Natural Log Calculator allows users to input a positive number and select a decimal precision to calculate its natural logarithm, display the exponential of the calculated log, and determine the inverse natural log with the chosen precision.

Step-by-Step Guide to Using the Natural Log Calculator

Step 1: Enter the Number

Begin by locating the input field labeled “Enter Number”. This is where you will input the number for which you want to calculate the natural logarithm. Please ensure the number you enter meets the validation requirements; it must be a positive number greater than 1e-09 and less than 1,000,000,000. The input accepts any number, but make sure it is positive.

Step 2: Select Decimal Precision

Next, move on to the input field labeled “Decimal Precision”. Here, you have several options for the number of decimal places you would like in the results. You can choose from the following precision levels:

  • 2 decimal places
  • 4 decimal places
  • 6 decimal places
  • 8 decimal places

Select the precision that best suits your needs by clicking on one of the options in the dropdown list.

Step 3: View the Results

Once you have entered your number and selected your desired precision, the calculator will automatically compute the results. The results fields are as follows:

  • Natural Logarithm (ln): This field will show the natural logarithm of the number you inputted, rounded to the selected decimal precision.
  • e raised to ln(x): This calculation demonstrates that applying the exponential function to the natural logarithm should return the original input number. It will be displayed with the same precision as selected.
  • Inverse Natural Log (e^x): In this field, the calculator will display the result of the exponential function applied directly to the input number. Like the other results, it’s shown with the chosen level of precision.

Review each result, making sure that the calculations meet your expectations. The calculator is designed to provide accurate results based on the inputs and selected precision, offering insight into both the natural logarithm and related exponential functions.
