Ah, great — I did not expect the factorial function being implemented even in the complex domain.

In double precision mode, i.e. 1 ULP = 10^—34, a value like 10^—17 or 10^—20 in R₀₀ yields 33 correct digits (...7216 resp. ...7215 instead of ...7213).

I always thought that FOCAL refers to FOurty-one CAlculator Language, i.e. the 41 series. On the other hand the features discussed here are unique to the 34s, so they should be named differently. Maybe THIFOCAL (thirty-four calculator language). ;-)

Gamma is why not factorial which is the same function really?

I tried quite hard to include complex versions of everything I could, the notable exception being the Riemann Zeta function where I couldn't find a suitable complex approximation.

That is all greek to me, my friend,
Its sense I would not apprehend.
About the meaning of this I've pondered,
"What the heck might that be?", I wondered.
My search has now come to an end. :-)

From the HTML sources:

PHP Code:

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> 


Thus you have to make sure to use UTF-8 in your posts.

OK - how can I set UTF-8 or any other character encoding while composing a message here?

Just compose your message! The encoding is already set by the pages of this site. Whenever you paste or type a non ASCII character, it is treated as Unicode and stored as such in the forum database.

You probably never have to handle this by yourself if your default-encoding is set to UTF-8. Your OS/editor/browser will translate the text to UTF-8 on the fly based on the encoding of the source.

You said I had to make sure the encoding is set to UTF-8. So what do I have to do to now? Where can I set the default encoding you mentioned?

On the Chrome browser go to Settings; search for Encoding; then select Customise Fonts in the Web Content section; scroll to the bottom, and there you are! No doubt something similar can be done in other browsers.

I don't see a need to set the encoding manually. Normally, the encoding of an HTML page is indicated in its header. All entry fields do just use the very same encoding as the page they are part of.

From the source of this page (the one I'm typing my reply in):

Code:

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

To be precise: The encoding may as well be indicated in the HTTP header as can be deduced from the "http-equiv" attribute.

Final words: Don't worry, just paste your special characters and you're done! If it doesn't work change your web browser.

Thank you – that's what I wanted to hear. ;-)
