WiSCy99 (Windows scientific and engineering calculator for real, complex
and matrix operation + grapher + unit converter) is a
comprehensive yet easy-to-use scientific calculator. Very thorough and
nicely designed, WiSCy is well documented and has a familiar and attractive
interface that makes it a pleasure to use. Features include support for
color graphs, integration, trigonomic functions, a variety of statistics
functions, a constants list that can be easily edited, unit conversions and
editor for custom units convertor, and lots more. You can even build and
edit lists of user variables and functions. All calculations are logged to a
"tape" that can be saved as text or printed. Graph plots can be also be
saved in one of three graphics formats.
Features List:
- Arithmetic and logical operators and functions
