As we all know, the calculator is a portable device we use everyday to do all kinds of maths — plus, minus, times, divide, root, all that. But got also scientific or atas calculators that can settle the confirm-difficult stuff like trigonometry functions, degrees, exponential operators, log functions, hyperbolic functions, square root, and so on. In this one, we going to build a calculator program using JavaScript.
Ln is what we call the natural logarithm, also the logarithm to base e. Here, the constant e is one number that is transcendental and irrational, roughly equal to 2.71828182845. The natural logarithm (ln) can be written as ln x or logₑx.
