vCalc is an advanced scientific calculator based on the Reverse
Polish notation used on well-known handheld calculators. Its
keyboard driven interface has been thoughtfully designed to be
both easy to learn and fast to use. vCalc supports a complete set
of scientific operations, binary math in hexadecimal and octal,
and has a sophisticated statistics engine that is designed to be
robust, even with difficult
datasets. vCalc also supports 100 memory registers, has a
10-level "undo" feature, and has the ability to save and load
data to disk.
See the tutorial for
operational information.
