G-Wizard Machinist's Calculator: Calculator
      
      Just your basic 
        engineering calculator, plus a whole lot more!
      The calculator 
        is tailored to the needs of a machinist. It does trig and unit conversions 
        and should be pretty self-explanatory. 
      Some things to 
        be aware of:
      - Angles for trig 
        functions are radians by default.
      - It's easy to 
        enter degrees and press the "RAD" button to convert to radians. 
        Press "DEG" to convert radians such as return by "atan" 
        back to degrees.
      - Use the D:M:S 
        button to enter angles in a variety of formats include degrees, minutes, 
        and seconds.
      - Press "Tenths" 
        to round the result to 0.0001, press "Thous" to round to 0.001.
      Unit Conversions
      
      The red underlining 
        shows the unit conversion and fraction functions... 
      Select the units 
        the calculator is using with the button next to the calculator's display. 
        Select the units to convert to with the button on the right. The screen 
        shot above shows an "inches to millimeters" conversion. If you 
        want to swap the units, press the "<-Use" button. The inches 
        and millimeters will exchange places. The Calculator can convert over 
        100 different units.
      There is a fractions 
        capability on the calculator. Press the "Frac." button to add 
        a fractional amount to the current value. For example, enter a "1", 
        press "Frac.", click "1/2", and the calculator now 
        displays "1.5". In addition, the "Frac." button will 
        display the fraction any time the calculator display is within a tenth 
        of any 1/32. So enter "0.375" and the button's label changes 
        to read "3/8". This makes it easy for you to deal with fractions.
      Keyboard 
        Commands
      You can use either 
        the mouse or the keyboard to operate the calculator. From the keyboard, 
        the Calculator responds to the following:
      - Digits (0..9) 
        and the Decimal Point (.)
      - Add (+)
      - Subtract (-)
      - Multiply (*)
      - Divide (/)
