yeah, doubles can store numbers of extremely high precision.
there's no way the chip manufacturers would write 2 versions of all that floating point stuff just for unsigned versions, i reckon.

You can't have unsigned floating-point values because there is no underlying hardware to work with them. Nearly everything uses the IEEE standard floating-point format, which uses one bit for the sign. Unsigned floating-point values wouldn't be that useful anyway...

Also, I believe if you truly have a need for more precision than doubles offer (doubles offer almost incomprehensible amounts of precision), you could probably get even getter with a library like GMP. Probably.

edit: checked it out:

High-level floating-point arithmetic functions (mpf). This is the GMP function category to use if the C type `double' doesn't give enough precision for an application. There are about 65 functions in this category.

I believe the "C" type double just refers to the IEEE format that drV mentioned; it's common, and not only C-centric

I don't know about that. I made an ogl solar system simulation, to scale, :lol: and Pluto was snapping into position, instead of smoothly gliding. I reduced the scale, and it moved smoothly. That was using just double though... I've never even heard of that GMP thing, until now.

I have added more content to the book. I am finally through with the data types and will begin in with the fun stuff. Right now the book is 166 pages, so the 200 page milestone is right around the corner.

Updated links in first post.

I love Garamond, but not this version. I'm not sure whether you are using the Adobe Garamond Pro set, but it comes with a Regular or Semibold (off the top of my head I can't remember which one is nicer) that I much prefer. The light version of Garamond is too weak in the main body of the characters for extended reading.

I could recommend some other fonts if you wish.

edit:

A little comparison showed me you're using standard Garamond. Check http://en.wikipedia.org/wiki/Garamond for a preview of the Adobe version, and you'll notice how it looks much more powerful.

Your call in the end.

I am using Garamond because that is the font that Lulu recommends for their copy. If you print the pages, you'll see that it is very readable.

For the final version of the PDF, I'll be using a screen font rather than a print font so that it is more readable.

I've printed both Garamond and Adobe Garamond Pro. Garamond looks weak (comparatively). Obviously, Lulu doesn't expect all it's customers to fork out $170 for a font, as most of customers are grannies printing their life's poems.

Nevertheless, Garamond is a good font for print. In fact, it's one of the better free ones. Initially I just wasn't sure if you were using the standard or Pro version. I wouldn't worry about it too much. Just make sure you print a text-heavy page on a laser printer somewhere before you send it off to Lulu.

Speaking of which, excellent selection of printer. Lulu is the best I've tried, and they've got a very very high quality of print. You won't be disappointed.

I haven't actually read any of the content, I just skimmed through for a couple of minutes. The only other thing that struck is the images. They didn't look of the highest quality. Could just be me.

I'll give it a read though. Proprs for the effort, in any case. I've tried and failed to write a FB-based book.[/i]

The images will change, they are just placeholders. I am still trying to get the first draft done, and I haven't done any edits at all, so the book is a bit of a mess. Normally, I would even post it in this condition, but people wanted to see it.

I am glad to hear that Lulu is a good POD publisher. This will be my first attempt at POD.

Thanks for the comments. I appreciate it.

Apart from a horrible and mentally scarring experience with cafepress, Lulu is really the only publishing service I've ever used. My grandfather wrote alot, and his publishers were vultures. He's passed away now, but I was recently talking to my grandmother about translating his work into English and getting it printed through Lulu. She told me even with the high printing cost, the profit given to you is good, at least by Indian standards. That pretty much set it for me.
