Could be adapted to FreeBASIC.

Some precisions about Thomas Kurtz on the Hewlett-Packard calculator forum:

Especially about his work with Einstein.

Here is a test using the MPFR library according to srvaldez (https://www.freebasic.net/forum/viewtopic.php?t=24110) The library has been compiled for 100 digits precision. The quad routine is called with 10 levels and a tolerance eps = 1E-90 ' ********************************************************...

The quad function has a sixth parameter err_est with a default value of 0. To return it, initialize it to a different value. dim as double err_est = 1 function f4(x as double) as double return 1-sqr(x*x-1)/x end function printf(!"integrate(1-sqr(x*x-1)/x, x=1..+inf) = %.15g\n", quad(@f4, 1...

Thank you for the reference. I have downloaded it.

For special functions I use mainly the MPFR library (thanks to your wonderful FreeBASIC binding), but it is always interesting to have new approximations.

Hello silverman ( I assume you are silverman from the Panoramic forum ? ) The position of the widget inside a group is defined relative to the main window, not the group. So you have to modiffy your coordinates: Fl_GroupBegin (Group_radio) Button_radio_red = Fl_Radio_Round_ButtonNew (10 + GNX, 5 + G...

The libfbmath.a file included in the FBMath distribution is for Windows only. So, it's uncompatible with Linux. You must recompile the library on Linux. Go to the modules subfolder of the FBMath distribution and run the compil.sh script. You will obtain the correct libfbmath.a, which then must be pl...

I have tested with Ubuntu 22.04 and FB 1.0.9 What is your problem exactly ? FBMath is not included in the FB distribution. You must download it from SourceForge : sourceforge.net/projects/fbmath Then you must recompile it for Linux. There are compilation scripts in the "modules" subfolder.

Thank you jepalza

I will check the emulator. It would be nice to convert some of these old BASIC games to FB, using the library.

For those who need only the Amstrad graphics, I have made a specific library : amsgraph.zip It's a static library, distributed as source code, with english documentation and 15 sample programs. https://i14.servimg.com/u/f14/16/88/76/65/fonts11.png https://i14.servimg.com/u/f14/16/88/76/65/caredi11.p...

How work it? With DLL? You can download it here: https://www.unilim.fr/pages_perso/jean.debord/fbcroco/fbcroco.htm There is a DLL which implements several procedures in FB for most of the CPC commands (MODE, ORIGIN, PEN, PAPER, MOVE, PLOT ...) You have also access to the Amstrad font and all its gr...

There is a project named "Crocodile Basic" on the PANORAMIC Basic forum to revive the CPC BASIC, using FB as the compiler.

It's all in french, though.
