ESBCalc - Freeware Calculator

ESBCalc - Freeware Calculator is a powerful scientific calculator that provides a great amount of features, including trigonometrical, hyperbolic and logarithmic functions.

You shouldn't get lost in the interface if you know exactly what you need, but ESBCalc - Freeware Calculator provides quite a complex interface that groups all available features right in the main window.

While it allows you to configure the number of decimals, ESBCalc - Freeware Calculator also boasts a memory tool, paper trail and even a history log to check previous operations.

The logarithmic functions can be used to calculate in base 10, base 2 and normal base, while also offering prefix functions to evaluate log.

Obviously, since it's such an advanced utility, it may all sound like rocket science to you, but you need to carefully use the available functions and it all becomes just a matter of time until you get used to it.

One of the downsides however is the fact that you cannot resize the window, so you're stuck with that small window that can be moved anywhere on the screen.

An “Options” screen lets you configure several parameters that concern the display, colors, paper trail and hints, so check this menu too if you wish to take full advantage of all its great features.

Overall, ESBCalc - Freeware Calculator is a handy piece of software that relies on a long lineup of features and although it has a number of minor drawbacks, there's no doubt it's one of the top products in this particular software category.
