Freeware
New Calc Lite for OS/2 released
|
Developer Magnus Olsson
released new version of Calc Lite for OS/2
(32-bit Scientific CLI Calculator ). This utility run in command line at the OS/2
prompt (photo above shows Calc Lite running in the Warp 4.0 of @Macarlo, Inc.).
The archive, CALC.ZIP (40, 4k) you can get it now, clicking the folder here:

The "Calc Lite" calculator is a freeware version
of the command line calculator included in the shareware WarpCalc. The only major difference is that this version is unsupported.
System requirements
Calc Lite is a 32-bit OS/2 application and should run
on OS/2 version 2.x and above.
Licensing
Calc Lite is freeware, but is copyrighted and not in
the public domain. Permission is granted to any individual or institution to use,

Documentation
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 behaviour. 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 used in conjunction with the trigonometric functions
is degrees. The defaults can be overridden through command line options as shown
below.
[ /not sci|fix|eng ][ /prec <n> ][ /unit
deg|rad|gra ]
This version introduces a new switch for ISO signs. This switch
forces the decimal sign to be a comma, the multiplication sign a dot above the line
and the division sign a slash.
[ /iso ]
To have the calculator use ANSI colors to highlight input
and results add the following switch.
[ /color ]
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. All
environment variables are case insensitive.
