www.vincs.it/VincSCalc key Features:

- One of the few calculators with resizable window (up to full screen) in order to allow a wide input/output field for huge numbers (horizontal) and deeply nested calculation (vertical).

- Nesting of calculation kept shown in calculation area that may become vertically scrollable for deeply nested calculation.

- Input/Output operand fields horizontally scrollable to allow arbitrary hugeness of integers (as huge as your hardware will allow)

- Numeric Keyboard disabled automatically when data is consistent to avoid involuntary overwrite (only operators or "clears" buttons are accepted)

- 5 "Memories Absolute" (MAx) on the left side of calculation area - these are used by the calculator in order to give extra output (see as example HMPx functions) - The panel can be horizontally shrinked to permit the widest calculation area as possible.

- 5 "Memories Editable" (MEx) on the right side of calculation area - the user can store results of operation by "input" arrow key in the dedicated panel as well as input directly a value inside the field giving also a "name" to any stored value in order to remind the meaning of such data (just close below the stored value) - Recall the value in the calculation area input it is so a simple as a click on the counter "output" arrow button in the panel. - The panel can be horizontally shrinked to permit the widest calculation area as possible.

- 3 Data Types (Double, BigInt[eger], XXLInt[eger])

- 4 numeric bases (only for integer types - decimal, octal, hexdecimal, binary)

- Calculations can be performed "run time", for a quick response, or also postponed to the "=" operator request to keep track and double check (RunTm checkbox is "run time" by default). - In case of postponed operations, the user could also eventually go back (çBkS button) in order to correct his input.

- Integer calculations can be performed in Modulo (settable directly in its field) allowing experiments with modular arithmetic.

- Integers primality test in probabilistic and deterministic methods.

- Integers HowManyPrimes precise functions to test the Gauss formulas (logarithmic, Integral Logarithmic) or the Riemann's derived formulas; among with this total. it will be possible to calculate how many primes are in the form m*k+/-n

- Numeric/Operators Pad of computer keyboard can be used for fast input by maniacs

- A dedicated primorial calculation button (x#).
