OpalCalc Portable

OpalCalc Portable is a software program that provides users with a simple means of making complex and simple calculations and comes bundled with multiple operations, functions, constants, examples, a multi-line environment and live answer capabilities.

You are not required to go through the installation process, as this is the portable edition of OpalCalc. As a result, the Windows registry and Start menu/screen are not going to be affected in any way, and no leftovers will remain on the disk after you delete it.

Another important aspect you have to take into account is that you can easily move the program files to a USB thumb drive, and thus take OpalCalc Portable anywhere with you and run it on any PC with just a few clicks.

This application enables you to open and save items using a proprietary OTXT file format, while only export is available using a TXT extension. Multiple instances can be opened in the same time thus enabling you to multi-task with ease.

A search function lets you find items with ease, while you can use a large number of built-in operators (more than, decimal point, multiply, divide, equality etc.), functions (min, max, average, median etc.), constants (quarter, pi, tau, million etc.) and variables (subtotal, total, false, hex etc.), while it is also possible to add your own and use an array of measurement units for area, density, mass, length, volume, speed and energy.

Examples are offered by the developers, so that you can easily see what types of calculations you can make. Moreover, you can zoom in and out, undo or redo actions, copy answers to the Clipboard and clone lines.

To wrap it up, OpalCalc Portable is an efficient piece of software when it comes to making complex calculations in real time. The interface is intuitive, the response time is good and the computer’s performance is not affected at all. Our tests did not reveal any errors, hangs or bugs.
