Operations Panel

The Operations Panel contains shortcuts to various commonly used functions, digits (like any standard calculator) and operators, such as plus, minus, divide or multiply. Choosing sto will popup a dialog, allowing you to choose a variable in which the most recent evaluation result should be stored. Selecting rcl shows the same dialog and allows to retrieve the value of a variable.

Note

Once a variable has been stored, it can be directly used in any calculation by simply typing it. For example, if you store 2 in the variable a, you can type a + 2 , which will yield, obviously, 4.

Choosing exe will execute the current expression, if any. Choosing off will terminate the Expression Calculator. The ans button retrieves the result of the most recent operation and places it on the Input Box.
