Operating Modes

ProCalc can be operated in one of five modes, scientific mode [Sci], and four binary math modes [Hex], [Dec], [Oct], and [Bin]. As you change modes, the calculator buttons change to indicate the different functions available. The number in the display is retained between modes, so that you can easily do number conversions between bases, as well as mixed calculations. Any numbers stored in the memories are also retained, and will be displayed in the current mode's format when recalled.

NOTE:  When ProCalc is switched to the basic 4-function mode, the calculator automatically switches to scientific mode with either an 8 or 10 digit display (depending on the display font setting in Preferences), decimal notation (no exponent), and a floating decimal point. The settings in effect when the switch occurred are restored when you switch back out of 4-function mode.
