Description:

Pc Calculator is a totally new kind of a calculator.
At the same time it is a handy text and formula editor and an advanced scientific calculator.
It works in an intuitive way and it is extremely user-friendly. For instance, all possible typing
errors are easily corrected and fast recalculated.

your calculations just where you wish. You can also add explanatory comments to remind
you what the calculations were made for.
On exit all the comments and formulas are saved and when you next time open the program,
it starts from the same position where it previously was.

examples
how its ingenious line and quote functions are used to create user defined functions
or to solve a system of linear equations in four variables.
And, in the long number mode calculations with very long numbers, over 200 digits, are supported, too.

What is new?
A major revision of Pc-Calculator was recently released.

which can be used to execute a constant, a function or a whole block of lines.
It has a large working memory for notes and calculations and it comes with a tutorial showing,
for instance, how three parameter user defined functions are created. As an example a calendar to
julian date conversion is given.
Julian date
is an easy method to count days between two calendar dates. The day of the week is also easily found.
In the compact mode the appearance of the program is also improved and you can start it
directly in this mode. See the screenshot below.
