The Master Calculator Module from Polymath Business Systems is a self-contained Omnis window that acts like a calculator desk accessory. You can use it along with any Omnis library. This product is available for users of Omnis 7 or Omnis Studio!
There are an incredible number of features included with this calculator. Besides the basic arithmetic functions, more advanced functions from the fields of mathematics, statistics and finance can be found. There are also a number of memory registers for storing intermediate or accumulated values. Visible memory registers include four general registers (A-D), X and Y registers that convert to "radius" and "angle" when the user toggles between x-y and polar coordinates, and six memory registers that are used by the annuity functions ann() and anna(). Other registers that are not visible include "count", "sum", and "sum of squares" registers used by the basic statistical functions and the "k" register used by the combinations and permutations functions. The calculator also supports an unlimited number of parenthetical levels in any calculation (limited only by memory), a "close all parentheses" functions, and a "last answer recall".
Entries and results are reflected on a tape display that is only limited in length by memory and can be printed to any destination supported by Omnis. The display can be fixed or floating for between 3 and 20 significant digits. Full precision is maintained in the background, but numbers on the entry line can be forced to round to a specific number of decimal places or to the nearest multiple of any number chosen by the user using the "rnd" function.
Numbers, basic arithmetic functions and certain other functions, and access to the letter-labeled memory registers can be performed from the keyboard and/or numeric keypad as well as by clicking buttons on the window. The current contents of the numeric entry line can also be copied to the clipboard and pasted into any field (in data entry mode) in the host application.
Although the Master Calculator Component ships as a "plain vanilla" window, tools are included in the Studio version to modify the color of the following items: background, buttons, fields, shadows, button text, and field text. The window will remember how it appeared when it was closed and re-establish that appearance when it is re-opened. Just click on the "Master Calculator Component" label to access the configuration toolbar.
