v7.9g (New Release 3/9/14)

Scientific/Financial/Geometry Calculator

for Windows 95/98/ME/NT/2000/XP/Vista/Win 7/Win 8

ProKalc (short for Professional Kalkulator) is a 32-bit Microsoft Windows scientific and financial calculator.  This version of ProKalc has a scrollable tape that shows the results of all calculations.  ProKalc is an improvement over the Windows calculator since it shows 15 digits with no rounding errors. ProKalc is intended for use with Windows 95, 98, NT, 2000, or XP and may not be used with Windows 3.11 and earlier versions. There is a 16-bit version of ProKalc (called SuperCal) available for use with Windows 3.11 and earlier. SuperCal can be obtained from the home page of this site.

ProKalc is a complete scientific calculator with the standard mathematical functions +, -, x, / as well as numerous math functions.  Included are powers, roots, reciprocals, percentage, absolute value, base 10 logarithms, natural logarithms,  trigonometric functions, hyperbolic functions, combinations, permutations, etc.  ProKalc has a 10-location non-volatile memory -- the value stored in each memory location is saved to file and reinitialized upon restarting ProKalc.

In addition to scientific functions, ProKalc is also capable of a full range of financial calculations.  Some of the possible financial calculations are dividend, profit/loss, present value, future value, loan calculations, various types of annuities, interest calculations, investment calculations, and currency conversions.

 The result of all calculations are printed to the calculator tape for review and all or part of the scrollable tape can be printed, saved to Windows clipboard, or saved to file.  The scrollable tape will hold the results of many calculations and will store well in excess of 1000 lines.  For those who prefer a calculator with no tape, ProKalc's tape can be hidden from view.

ProKalc is very intuitive and easy to use.  Even so, integrated help is available throughout the program giving help on all calculator functions.  The user also has the ability to turn a 'hint' feature on so that a small pop-up hint box appears as the mouse cursor is moved over the buttons on the calculator face. The latest version allows the user to configure many features in the program, including window location and the color of various screen elements.

Windows XP Themes capability has been added as of version 7.7a of ProKalc.

An installation utility is included to get ProKalc up and running on your system.  ProKalc is compatible with Windows 95, 98, ME and Windows NT, 2000, XP, Win7, and Win8..

ProKalc is very useful for students, professionals, engineers, educators, businesspersons, and homeowners.

Beginning with version 7.9c, ProKalc uses a new installation utility based on InnoSetup, a very popular program for creating installs.

Beginning with version 7.9c, ProKalc is compatible with Windows 7 and 64-Bit versions of Windows XP, Vista, and Windows 7.
