IonCalc is an expression based calculator, and very
easy to use, keeps the last 10 expressions for reuse
or edit.
As a graphics calculator, IonCalc displays graphical
representations of expressions, formulas or data in
different chart types.
The entire state of IonCalc can be saved and read, so
you can continue with your previous work when you
launch the program.
Easily converts units with a single command.
It has a built-in, simple and powerful programming
language, similar to Basic, to add functions for use
in expressions or your own functions.
Operation results can be stored in variables; the
number of them is limited only by the memory of your
computer. You can store any value (real, matrix,
complex or string) in any variable. The same is
applicable for the user-defined functions.
Functions can be defined and debugged with the
integrated editor. You can stop the function execution
and inspect values of any variable to catch bugs, if
any, faster.
