Unlike most calculators, QuickCalc is an expression builder. For greater flexibility,
it does not immediately calculate an answer when you click a function. Instead, you
compose an expression that you can easily edit and, when you are finished, you click
the equal sign (=) or press Enter. Later, you can retrieve the expression from the
History area, modify it, and recalculate the results.

With QuickCalc, you can

• Perform mathematical and trigonometric calculations
• Access and review previously entered calculations for re-evaluation
• Use the calculator with the Properties palette to modify object properties
• Convert units of measurement
• Perform geometric calculations related to specific objects
• Copy and paste values and expressions to and from the Properties palette and the Command
  prompt
• Perform computations on mixed numbers (fractions), and feet and inches
• Define, store, and use calculator variables
• Use geometric functions from the CAL command
