ESBCalc Portable

ESBCalc Portable is a freeware scientific calculator that’s not only very easy to use, but also fully portable to be used on the go.
The program’s GUI is not at all complicated if this isn’t the first scientific calculator you’re using, with all functions nicely organized in the main window for instant access.
Obviously, keyboard support is available, which means that you can do any operation without the need for a mouse, although you may need it when using special functions such as trigonometric, hyperbolic or logarithmic.
A settings screen is included too, providing access not only to various configurable parameters, but also to three different constants, namely gamma, gravity and speed of light.
As for the options, you can tweak the display by enabling XP style buttons and thousands separators or by changing colors. Additionally, users are allowed to enable hints that are supposed to lend them a hand when using specific functions included in the calculator.
It’s not at all a surprise, but it’s worth mentioning that ESBCalc Portable works flawlessly on all Windows versions, obviously without the need for administrator privileges on Windows 7 workstations. Additionally, it’s fully portable, so you can copy its files on a removable drive and use it on another computer without prior installation.
All things considered, ESBCalc Portable is a very handy scientific calculator. The program’s GUI doesn’t assault the user with complicated features, the settings screen is mostly focused on display options, while a basic help manual makes sure you figure out how to take the most out of each feature.
