ESBCalc Pro

ESBCalc Pro is a feature-rich and stylish application that offer elementary options, accessible even for novices,  to do simple calculations, such as addition, multiplication or divide. It also features more complex elements (square root, logarithm, radian), and can handle functions as well.

The layout is neat and easy-to-use, sectioned into a paper-like history panel, and the buttons, located underneath it. They could have been structured in a more organized way, to divide the functions from the numbers. The values are inserted like you would normally do, by writing them and picking the proper operation symbol.

For a quicker insertion, you can opt for the Numpad keyboard to enter your values. The basic set of operations that can be done are the addition, division, subtract, and multiplication. You can calculate the square root, radian, cosine, sine, tangent, cotangent, inverse, hyperbolic, and natural logarithm.

For each component, a preset hotkey combination is attributed, which, unfortunately, can't be modified with custom ones. You have the option to copy the whole results or just a single line to the clipboard and used in your homework or school projects.

However, if you need to do multiple calculations, the memory function comes in handy to recall the previous result. The help file brings detailed explanations about each element, in case you have doubts. From the options, the app lets you change the display style and text colors, choose the thousand separators, enable the tool tips, and assign a hotkey to show the calculator.

Taking everything into consideration, ESBCalc Pro is a reliable and user-friendly calculator designed to help you to do standard mathematical calculations, as well as more complex functions. During our testing, the tasks were executed swiftly and without error.
