About

KCalc has everything you would expect from a scientific calculator, plus:

  • Trigonometric functions, logic operations and statistical calculations
  • A results stack which enables convenient recall of previous calculation results
  • Precision is user-definable
  • The display allows cut and paste of numbers
  • The display colors and font are configurable, aiding usability
  • The use of key-bindings make it easy to use without a pointing device
