Hi Gang.
Here is the new WarpCalc by Magnus Olsson, currently in beta test. WarpCalc is a serious calculator for serious OS/2 users. I'm registered user, purchased my license from BMT Micro, Inc., as you can see in the photo below:

 Catalog:  http://www.bmtmicro.com/catalog/warpcalc/ (v1.84a)
      Home:  http://www.visdom.nu/home/warpcalc/
      Support:  warpcalc@visdom.nu (bug reports, requests, etc.)

In the photo above you can see the WarpCalc popup menu with several options

The WarpCalc calculator package contains two scientific calculators, one for the OS/2 command line (CLI) and one for the OS/2 Presentation Manager (GUI). Both versions share the same core capabilities. In addition to common calculator features they allow the user to define his/her own symbols.

Both the CLI version and the GUI version are 32-bit OS/2 applications. Calc should run on OS/2 2.x and above. WarpCalc runs on OS/2 3.x (Warp), but Warp 4 or later is recommended for visual appearance. WarpCalc uses the WarpSans font introduced with Warp 4. For Warp 3 users not having this font it can be installed by replacing the Warp 3 version of the file dspres.dll with an updated version downloadable from the WarpCalc home page.

 WarpCalc is shareware. The great thing about shareware is that you only have to buy what you use. The 30 day trial  period is absolutely free, but if you decide to use WarpCalc even after this trial period have expired you must register the software. The one-time cost of registration grants you a lifetime license to use this version and all upgrades on one computer at a time.

Installation

Neither the CLI version nor the GUI version requires any special installation. Simply copy the included files to a directory of your choice.

If you are using Warp 4, the WPS will create a program object for WarpCalc when you drag the executable to your desktop. If you want to start WarpCalc from the desktop popup menu follow these steps:

      1. Click mouse button 2 on the desktop.
      2. Select "Properties" from the menu.
      3. Click on the "Menu" tab.
      4. Drag the WarpCalc program object over the
         "actions on menu" list box and drop it.

 Documenting the CLI version

      The command line version can be passed a mathematical
      expression as a command line argument like this:

      calc pi

      The above command evaluates the name pi and displays the
      result using default settings. It then immediately returns
      to the command prompt.

      It is also possible to enter more than one expression at
      once, separating the different expressions with semicolons.

      calc "x= atan 2; sin x/cos x; tan x - ans"

      The first expression assigns the angle for tangens 2 to x.
      In the following expression the value of x is used to
      calculate tangens for x. The last expression should give
      the result zero (ans holds the result from the previous
      expression).

      When starting the command line version without passing any
      expressions the program will display a command prompt. From
      that prompt you can evaluate mathematical expressions and
      configure the calculators behavior. The prompt shows the
      angular unit currently used. Online help can be displayed
      by entering the internal command 'help'. For a list of
      help topics enter: 'help ?'.

      As a default the calculator uses a flexible result notation.
      Except for fix point notation the default precision is 15
      significant digits (fix point notation uses 15 decimals).
      The default angle measurement unit used in conjunction with
      the trigonometric functions is radian. The defaults can be
      overridden through command line options as shown below.

      [ /not sci|fix|eng ][ /prec <n> ][ /unit deg|rad|gra ]

      To have the calculator use ANSI colors to highlight input
      and results add the following switch.

      [ /color ]

      For U.S. based users there is also a switch to force the
      calculator to use ISO signs for decimal separator,
      multiplication and the division.

      [ /iso ]

      Defaults for the command line switches can be set through
      the following environment variables: calc_not, calc_prec,
      calc_unit, calc_iso and calc_color. The options are the
      same as above except for calc_iso and calc_color, which
      take either a yes or a no.

      [ set calc_pos= <column> ]

      By stating the above in config.sys or directly at an OS/2
      command prompt you tell the calculator what column position
      to use for the last digit of the results. The default,
      far right, position may be inappropriate when in fullscreen
      mode. To fix results at column 40 simply specify:

      set calc_pos=40

      Note that all environment variables are case insensitive.

      The internal command line works as follows. A block cursor
      indicates over-write mode and a line cursor insert mode.
      Escape erases the current input. Input history can be
      navigated with the up/down- keys.
