WHAT IT IS...

  The Ultimate Calculator (Ucalc), written by Daniel Corbier,
represents a considerable amount of time, effort, and knowledge
of the subject at hand...  numbers.

WHAT IT's NOT...

  It's not a TSR, taking up background space... and it's not a
constant running program.  It's an executable item that is placed
along your "PATH" somewhere, so it can be called from anywhere in
your system.  Simple as that.  Now you CAN load it as a prompt to
do multiple computations...

---

  Perhaps an introduction is in order.  Ucalc is a high precision
scientific calculator which can evaluate expressions, solve
equations, perform numerical integrations, and do summations.  It
supports many built-in functions, operators, numerical notations,
and modes.  It also allows for user-defined functions and variables!
Expressions such as the following can be computed:

   63 - 5 + 4.821

   (5.9-abs(2.8/5-3))^2 + sin( 3-(pi+3/4) )

   sum(x^2+x-2,1..500)

   solve(3*x^2+2*x-5=27)

   integ(x^2*sin(x),1..5)

   #b101010 and (#b10101 or #h1CC) * 2^5

   15 * sin(pi/4)+abs(10-(5+log(20))^2+9)-#b101110111

  How's that for calculations.   If you can express it in terms that
Ucalc can understand, you can solve almost anything.  If you are
already versed in the ettiquette of high level math functions, then
you are going to have an absolute ball.  (grin)

  Here's some of the functions and features you can expect:

- Online help with F1 key
- High precision: 18 significant digits. Range: 3.4E-4932 to 1.2E+4932
- Flexible notations: ** or ^, SQR or SQRT, MOD or % etc...
- Line editor with expression recall
- Text buffer:  it can keep the last 100 lines to be recalled!
- Summations
- Numerical Integration
- Equations can be solved
- Hyperbolic functions
- Trig functions w/radian, degree, and gradient modes
- User defined functions and variables
- Arithmetic, Bitwise, and Relational operators
- Adjustable FIX notation
- Decimal, Hexadecimal, binary and/or Octal notations
- HBO mode...Get your result in hex, binary, AND octal notation!
- A file with calculations to be performed can be created ahead
 of time with your favorite editor, and passed at the command line!

- and other neat stuff.

  According to Ucalc's author, it has been tested under DOS 4.01 & 5.0,
4DOS 4.0 & 4.01, Desqview 2.42, DV/X 1.10, QEMM 6.02, 6.2 & 6.3, VPIX,
DPMI, Windows 3.1 and Stacker 2.0.
  I can personally attest to it working on my system under: DOS 5.0,
QEMM 6.0, Xtra Drive, and assorted things I have running at any particular
time.  It's very handy, and takes up very little room, storage-wise and
in working memory.


Comments:

  All in all, I liked this item, and heartily support it.  It is as
user friendly as it can be considering the depth of functionality,
and practical for the knowledgeable user.  Check it out...

  I like the program very much, and think it wouold be a great tool for
use by college students/engineers.
----Reviewer: David Branson


  I had trouble using it since I am not a math student and because I wasn't
sure what all the functions ment.  I know that this is my problem, but felt
it would have been nice to have some kind of tutorial to explain things to 
me. This program is great for those that are familiar with using a scientific
calculator's. It was fun trying to figure out items & functions.
