# Logarithm Calculator

The calculator will find the logarithm (natural, decimal, etc.) of the given value to the given base ($$$e$$$, $$$10$$$, etc.).

The domain of the logarithm is $$$(0,\infty)$$$, the range is $$$(-\infty,\infty)$$$.

If you enter the value outside of the domain, the result will be a complex number.

If you enter a negative base, the result will be a complex number.

It is neither an even nor an odd function.

## Your Input

**Evaluate $$$\log_{e}\left(20\right) = \ln\left(20\right)$$$.**

## Answer

**The value is $$$\ln{\left(20 \right)}\approx 2.99573227355399$$$A.**
