vCalc is a scientific calculator that uses RPN notation and can perform a wide range of mathematical, binary, and statistical operations. It is keyboard-driven and offers a complete set of features found in other scientific calculators.

vCalc comes equipped with a comprehensive set of math, binary, and statistical operations, including sine, cosine, and tangent, as well as their inverses. Additionally, there are a plethora of other features that make vCalc an exceptional tool for scientific calculations.
One of the best aspects of vCalc is its keyboard-driven user interface. This makes it easy to operate the calculator without the need for a mouse or other peripherals. You can save time and increase your productivity by entering commands with just a few keystrokes. Moreover, the four basic operations on integer and floating point numbers are easy to access and use.
Another great feature of vCalc is its support for 100 memory registers with a real-time watch capability. This allows you to quickly access previously entered data, saving you time when performing repetitive calculations. There are also exponent, square root, %, %T, and Delta % functions, as well as log and antilog options in bases 10, e, and 2.
vCalc also offers functions for advanced operations such as floor, ceiling, truncate, round, and absolute value. You can also calculate factorial/Gamma functions, and perform one- and two-variable statistics with multiple concurrent datasets. This software supports curve fitting (linear, logarithmic, exponential, and power), as well as 64-bit integer math with bitwise AND, OR, XOR, and NOT.
The ability to display and enter integers in decimal, hexadecimal, and octal is an added convenience provided by this calculator. Also, vCalc allows you to save and load your work to disk and provides clipboard Cut, Copy, and Paste options. Finally, the software is fully IEEE-754 compliant, ensuring accurate results for all your calculations.
Overall, vCalc is a fantastic scientific calculator with a host of advanced features that are both user-friendly and make complex calculations a breeze.
