Calculate the natural logarithm of a number.

`LN(number)`

- number - the real number to calculate the natural logarithm of

`LN(86)`

The LN function in Sourcetable returns the natural logarithm (ln) of a given number. For example, if we wanted to calculate the natural logarithm of 86, we would use the syntax above, which returns the value 4.453429.

`LN(2.7182818)`

The LN function can also be used to calculate the natural logarithm of the value of a constant. For example, if you wanted to calculate the natural logarithm of the value of the constant 2.7182818, you would use the syntax above, which returns the value 0.9999999.

`LN(EXP(3))`

The LN function can also be used to calculate the natural logarithm of the result of another function. For example, if you wanted to calculate the natural logarithm of the value of e raised to the power of 3, you would use the syntax above, which returns the value 3.

The LN function calculates the natural logarithm of a number based on the constant e. It takes a positive real number as an argument.

- The
**LN**function is the inverse of the**EXP**function, which models exponential decay. - The
**LN**function takes a positive number as its argument.

The LN function calculates the natural logarithm of a number.

The inverse of the LN function is the EXP function.

The LN function takes a real number as its argument.

Yes, the argument must be positive.
