Hi Ken

Here is a link to the NIST online mathematical library; it is updated on a regular basis from what I can tell and is a companion to the book (no longer in print).

Hi Ken

I updated the code with your latest revisions and it worked fine; the results match the output from Python using cmath as a check.

Interesting point, but Scilab and Octave both give the o ...

Thanks for the update Ken. Certainly is an interesting problem.

Hi Ken

I had a look at tweaking the module to cover all domains and it seems to work (so far) with your modifications.

Hi Ken

Good to see you found a solution to the problem.

Hi Ken

I tried a test code and get some values close to the expected result but it falls over for large values as a complex input to acos.

Using the explicit functions for acos and asin as func ...

Hello,

Just wondering if anyone has managed to build the netcdf Fortran module to work with FTN95 or if there are other ways to deal with netCDF in Fortran?

The code is rather involved!

Quick update.

Came across an old bit of code I had and this command works without issue for a long string:

Thanks for the info Paul.

Shame Clearwin cannot read Inkscape SVG files directly; the structure is slightly different.

Thanks for the pointers.

Does Clearwin accept SVG files as input?

Thanks Ken for the pointer to the Clearwin examples folder; that really helps.

Have updated the existing code with sliders for mass and velocity which worked! It is a start, but interesting to lear ...

Thanks Ken for the code idea, that works for the basic structure I was looking to build.

Found the guide Paul, that will be a good start; a bit of a learning curve.

I did try to load the origina ...
