TSE: Floating: Point: Calculations: DLL: tsemathscientificcalculator.s

Hello,

1. Note: If this program shows its usefulness I would propose to maybe add the .dll

to a new directory '<TSE>\math' and to add the .s file to the 'potpourri' menu

in TSE and to publish this in e.g. the next release of TSE.

2. This will add floating point to TSE.

3. If any issues seen, please let me know.

4. Here a TSE program 

(based fully on original earlier source code of Rick Hodgin,

but I used Claude AI + DeepSeek to add more functionality

to it.

5. Including a full parser of mathematical expression input.

Examples:

 2 * sin( 1 ) = 1.68294191

 2^3^4 = 64

 -3 * -4 = 12 

 sin( 1 ) * cos( 1 ) * sinh( 2 ) * cosh( 1 ) = 2.54445863

6. Optionally: To double check the result you can e.g. copy/paste the expression also to (Google) browser addres bar.

7. Implemented functions e.g.:

+, -, *, /, ^, abs, ceiling, cos, cosh, exp, floor, log, log10, mod, rad2deg, sin, sinh, sqrt, tan, tanh, e, pi, log10

Steps:

1. Download the tsemathscientificcalculator.zip file

    https://knudvaneeden.com/temp/tsemathscientificcalculator.zip

2. Unzip the file somewhere

3. Put both 

    tsemathscientificcalculator.s 

   and 

  

    tsemathscientificcalculator.dll file 

in the *same* directory.

4. Compile tsemathscientificcalculator.s in that same directory

5. Run the tsemathscientificcalculator.mac in that same directory

Note: Optionally: the tsemathscientificcalculator.c file could be compiled

by using Borland C++ command line compiler version 5.5 using

 bcc32.exe -tWD -I<pathtoyourborlandincludedirectory> -L<pathtoyourborlandlibdirectory> tsemathscientific.c

and that will then create the tsemathscientificcalculator.dll

with friendly greetings

[knud van eeden]

1. Additional functions: asin, acos, atan (which give the inverse value of a given sin, cos and tan).

2. In case of always download the latest version first, as things change:

    https://knudvaneeden.com/temp/tsemathscientificcalculator.zip

3. Of course you can now additionally add your (basically any) (scientific) floating point calculations to your TSE programs by including the necessary information (DLL, ...)

4. Now TSE has floating point 

(similar to e.g. editors like SlickEdit who has this floating point ability already long since).

5. Note: In case of incorporating tsemathscientificcalculator.dll in TSE it can also be put in the TSE main directory, similar to e.g. 'spell.dll' there. 

6. Note: It is a (very) small DLL, something like 35K file size.

Let me know if anyone wants math/float functions in TSE that are implemented using the macro language instead of an external DLL.

They would be much slower than Knud’s solution, but can be made as flexible as required.

I have been looking into it a bit and find it fascinating, but I have no practical use cases for such functionality.

Carlo, 

It may be slower but you will be able to also use it on linux.

Excellent point!
Other features could be numbers with an extreme amount of digits and not-rounded rational numbers.
That said, so far my idea seems to be a solution in search of a problem.

At the moment I do not believe that is possible.

One would have to develop all these functions like sine, cosine, tan, arcsine, arccos, arctan, e power, logarithm, ... 

and exceptions.

Maybe some operations like add, subtract, multiply, divide, ...

but still a very big major effort if ever ready assumed...

> It may be slower but you will be able to also use it on linux.

At the moment I assume it would very possibly possible to recompile that C DLL to a Linux equivalent also

using gcc. That could maybe be done in a few minutes to few hours of experimenting.

[knud van eeden]

I am pretty sure at this moment if I should ask Claude, DeepSeek or ChatGPT AI it will give me an answer in a minute

(=from Borland C++ version 5.5 command line compiler to gcc instead and a Linux DLL like answer (I know, you can

not use DLLs on Linux they have their own equivalent).

[knud van eeden]

I realize now, the problem is that one can have such Linux DLL like solution, but we have no possibility in TSE built-in to use that in Linux as far as I know, so this conversion method Windows -> Linux is not going to work at all I assume at this moment. So will not be tried in the current state of TSE.

[knud van eeden]

So on Linux one would use the external executable like

 zzcalc 

developed by 

Zhong Zhao.

Or one similar solution created by me later some day.

Well, only the ones that are needed and asked-for, but yes, that could be all of the above and more.

Nah.
I read your "ready" reference as referring to writing the macro.
That would actually be exceptionally easy.
All these functions have finite algorithms, where finite is determined by the required precision.
For example, the sine and cosine functions can be calculated using a Taylor series,
and the other circle/wave-functions are derivatives of these two functions.
Most of my macro-writing time is spent on anticipating user interaction,
and I am beginning to develop a love/hate relationship with configuration menus.
There will be no configuration menu for a math macro!
This would be sooo easy :-)

The macro's weak point would be calculating the sine for 10,000 angles each consisting of 10,000 digits.
Its run-time might be longer than it would take me to write the macro. :-)

Which brings me back to there currently being no practical use case for such a macro.

Very good point, that is what I kind of knew about it at this moment also without having looked into it further.

But ...

Taylor is all about derivatives, first, second, third, ... derivative.

So those values would have to be calculated somehow first (probably some combination of floating point add, subtract, multiply, divide, ..., maybe power)

What is needed is thus an expression evaluator. E.g. you input something like

"3 * sin( 3.1415 / 2 ) - 2^3 + 5 / 6"

I have such in my tsemathscientificcalculator.s and also Zhong Zhao has it in his 'zzcalc.s' (='Z'hong'Z'hao'CALCulator.s).

But mine does still have some issues (e.g. 0^0, 0^(1/2), ... so gives wrong answers in special cases, ... (thus errors as far as I know), so that will have to be improved further some time).

> What is needed is thus an expression evaluator

The simplest solution for this is 'Dijkstra's double priority' algorithm.

You create a table with 2 priorities per operator (priorities you choose so that e.g. '*' has higher priority than '+' and so on...).

Your given infix expression you parse, put the operators and the operands on a stack and convert to a postfix (RPN) expression.

The resulting stack you then parse from top to bottom and pull the operators and operands from it using that defined double priority.

[knud van eeden]

Here is a significant example of where applicable using a TSE SAL floating point implementation:
