Introduction 1

CCCalc ^(*) is a simple tool for simple calculations.

It performs four basic arithmetic operations, percent calculations and also calculates square roots. It allows you to have as many digits in your numbers as you need without limitations. Number of fractional digits and rounding-off are tunable.

CCCalc saves the whole calculation history automatically and thus allows you to correct any misprint at any moment, or easily reuse previously typed numbers or expressions.

It provides the complete set of memory operations, such as memory add or subtract. Memory volume of CCCalc is not limited to just one slot. This memory is also visible and even editable.

To calculate with CCCalc, simply use the same key sequences as for an ordinary desktop or pocket calculator. The response shall be as expected.

Corrections can be made as for an ordinary computer text: set the caret to a certain place of the text and then delete wrong characters and/or type missed ones.

There is a number of differences between CCCalc and text editors though. They all arise from the idea that the "text" in CCCalc shall always represent a valid mathematical expression which can be calculated. To achieve this, CCCalc sometimes ignores some keystrokes or sometimes performs more action then it can be expected. Such derivations are described in subsequent pages.

^(*) Name CCCalc is an acronym for "Check-n-Correct-Calculator".
