Jac
Jac is a simple calculator that can be run in the console or with a GUI.
Jac is a straightforward calculator that functions both through a GUI and a terminal. On the GUI, skins built on the OYOAHA framework can be used. In addition, the GUI may store sessions to a file and shows previously performed activities. Infix notation is the only notation used for all operations. Roots and exponents are accepted. When writing scripts and you might need a calculator, console mode comes in handy. Version 1.1.232 includes updated help documentation and correct programme logging functionality via the command line.
