Business Calculator

Yes, rpsoft2000 is the author of this software.  However, we ourselves are still tickled with this new business calculator that has been added to the convert 2000 software package.  It has rapidly become almost the only calculator that we use any more.  It features a simulated paper tape readout that shows calculations as you go.  Hence it is excellent for balancing check books, or accounts, or even for usage as a temporary software cash register.

Included of course are the normal functions of addition, subtraction, multiplication and division.  But it also includes some more features as percentage help, some cash register functions, a visible ten item memory, and even some buttons for custom constants that you can set up - such as commission rates.  If you wish, the business calculator also can send its output to the default printer connected to your computer.

Simulated Cash Register functions include "tax and total" for calculating tax and showing it separately, and then the total.   "Cash and Change" which allows you to enter the amount the customer pays and then calculates change.  And "Credit Card" which allows for a signature below for customers to sign.  You can also add a custom name of yourself or your customer at the top of the tape print - within certain length restrictions of course.

More:  Keyboard "hot keys" allow you to control much of this calculator from the number pad on your computer

NEW Optional Scientific keys

If you look at the small button in the middle upper right that says "SCI >".  clicking this button opens the business calculator wider and shows the first bank of scientific keys.  The two items at the bottom are different and you go from the image on the left to the image on the right, you would use the lower right button "More?" in order to get the second bank of keys.  And of course the lower right key on the image on the right labeled "Back?" again takes you back to the rist bank of keys.  Note also on both of these that the "SCI >" button in the blue area upper right now says "BUS <" and of course therefore takes you back to the business secition.



We tried to include the most commonly used functions in this second.  Notice also the for each bank of keys that there are two rows of scientific keys.  In many cases the button on the right is the opposite of the button on the left.  For example, squaring an item x2 has the square root just to the right of it.  So how does it work?  Let us say that we begin with 5 in the accumulator.  We will just put it there.  Then when we use x2 it will "square" the accumulator, which means multiplying itself by itself.  So then the answer, 25 would show in the accumulator.  Now if we use the button on the right, the square root, of 25, we would again go back to where we began - at "5" in the accumulator.

Notice also that for trigonometry functions that we give the option with bullet choices for either working in radians or degrees.  Note that there are also buttons that just modify something from degrees to radians also, if you wish to do that also.  On the second set of scientific buttons we do include n!  which will give a factorial answer.  There also is a "distr" key which you would press in order to begin entering a series of numbers.  Up to 500 of them I believe.  And you would press "enter" after entering each item in this list.  Then when you press the "distr" key again will then work on the data and tell you the average, the norm, the sigma, the highest entry, the lowest entry and a few other items about it.

The scientific keys do not repeat on purpose as do some of the normal business +, -, x and / (divide) keys can.  We did this to ensure no odd complexities or confusion.

Overall - Convert 2000 is a collection of Six Calculators

  • Business Calculator A computer calculator with some excellent features.  It includes a simulated paper tape readout on screen that shows calculations as you go - and it can also print to a default printer.  It also includes 10 memory locations that are visible to help you remember which memory value is which.
  • Metric to English Calculator: that includes conversions for:  weight, distance, volume, temperature, hexadecimal to ascii and decimal, and quality sigma to ppm
  • Mortgage Loan Calculator: that allows you to calculate any of the four items of:  Principal (amount of loan) , interest rate, term of loan, or payment amount by entering the other  three.  An amortization schedule that also allows save and print is included.  Many options.
  • Quality Calculator:  Many Handheld calculators will do statistics.  This one does not.  What it does do is include many items not found on hand held calculators including mtbf calculations, and the relationship between mtbf, mttr and system availability.  Also includes ppm to sigma calculations plus fahrenheit to celsius conversion.
  • Chinese Calendar Calculator:  This calculator is a simplistic approximation of the Chinese tradition of naming years after animals and how it relates to our own Gregorian solar calendar years.  It is a simple approximation, and is mostly included for fun.
  • Custom Calculator:  Allows 9 lines of programmable calculations.  It does not include all programmable functions, but includes many of the common ones such as addition, subtraction, multiplication, division, %, logs, natural logs, exponentiation, and more.  It does not allow parenthesis but does allow multi-line information transfer at least in a downward direction.  This can be set up for many common small business needs.  Examples included within the calculator.
  • Cellular Calculator:  This might be primarily for those in the cellular business.  It can translate cellular serial number for small or large (two types) of serial numbers between decimal or hexadecimal.  And no, it is not just a simple overall conversion.
  • Odds Calculator:  Gives three different sections on the screen that can help calculate odds for some common items.  The help screen for it also provides examples and how to set up odds - something you might find both fun and interesting.
  • Hunting Calculator:  Provides some basic information for speed and gravity for items thrown or shot.  As soon as an item is thrown or shot, gravity causes it to fall.  How much do you need to compensate for?  If skeet shooting at a moving target, how much to lead it?

Overall - Of course, with differences in definitions and rounding techniques, you will need to check settings and ensure suitability of these calculators for your own needs.  However, this software can be an exceptional help when you need it and it comes at a very low package price.  Switch from one calculator to another by simply clicking on the calculator you wish on the pull-down menu that it is on each main calculator screen.  An option file can remember your settings if you wish it to be saved.  Load and save of multiple options is also provided for.
