## Natural Logarithm Calculator

### Ln Calculator

The Ln calculator is used to determine the natural logarithm of a number. It uses simple formulas in performing the calculations. It has a single text field where you enter the Ln value. Mostly, the natural logarithm of X is expressed as; ‘Ln X’ and ‘logeX’. They are commonly used in some of the scientific contexts and several other programming languages. The logarithm to the base ‘e’ is the natural logarithm and is approximately equivalent to Euler’s number, 2.718281828.The Ln Calculator has two controls which are used to perform different functions. The ‘Calculate’ button is used to execute the conversion of the values entered in the blank text field. Your results will be displayed in the bottom platform of the calculator. The ‘Reset’ button is used to erase all the text fields of the previous calculations. It is the quickest way of resetting the calculator whenever you want to perform new calculations.

##### For example;

Find the natural logarithm of 45.##### Solution;

Enter the number 45 in the blank text field and then click the equal sign or the ‘Calculate’ button. They both work in a similar way, giving you accurate results depending on the value entered in the text field. The answer will be displayed as; 3.8066624898The natural logarithm calculator can also be used to calculate the decimal values.

##### For example;

Find the natural logarithm of 0.5##### Solution;

Enter the value 0.5 in the blank text field and then click the equal sign or the ‘Calculate’ button. Your results will be displayed as; -0.69314718056You can also use ‘e’ to express the scientific notation. It is important to know that the calculator will give accurate results depending on the values entered in the text field. There are various ways in which you can enter the Ln values. E.g. 6e2, 4e-7, 5.78e10

##### For example;

Determine the natural logarithm of 8e5##### Solution

Enter the 8e5 in the blank text field and then click on the equal sign or ‘Calculate’ button.Your answer will be displayed as; 13.592367007
