GrandCalc is a simple calculator with a modern look and feel, though excellent for computing logarithms in particular. It’s straightforward from its first launch: enter your input and go!

It has a clean display of numbers and expressions in a split view. These areas are collapsible, and you can move across a long number using the left- and right-arrow keys on your keyboard. When you press the Enter key, any new input is calculated.

It has a searchable built-in record for each operation (you can change it from All to Latest and even Last Operation to track the last one) that can be printed more...
