Scientific Notation?

There is another way to get the scientific notations. At least the square and cube notation.

From windows, click Start, bring up All Programs, then Accessories then System Tools, then Character Map. The numbers can be found on the chart.

eg. (2²= 4) (½² = ¼) & other symbols, like the ones that describe my woodworking setups, such as ± or ~. Degrees (°F) notes are also there.

I think the terms you are looking for are superscripts and subscripts. BTW not all font sets have extended sets and not all font even with the same names have the same sets of extended ascii.

IIRC, it was one of my high school math teachers that passed along this bit of trivia (although it might have been the Latin teacher while we were translating the latin description of Hannibal's invasion across the Alps):

in Egypt, the Nile used to flood every year. the good news was that this left fresh silt in the fields and served as fertilizer. the bad news is that it wiped out (most) all the boundary markers for the fields. trig was developed as the art of surveying to re-mark the property boundaries each year after the flood.

If you click on an entry in the table(character) AND then click on 'select', it places a copy in a temporary area(more than one character may be so copied to the temporary area). You can then click on 'copy' which will place all those characters in the 'temporary area' in the clipboard.

When editing a post, you then paste the characters from the clipboard.

Now that IS more trouble than doing an ALTxxx, but it reveals ALL the characters in the font being used. This includes the extended character set(those ABOVE 256) which are NOT accessible using the 'ALT xxx' method.

One other 'detail' This MAY be a feature of 'power toys for windows' and NOT contained within a vanilla windows program set. If you cannot find it in \windows\system32, holler!

Got it!!! Nice little trick!! Thanks. Windows Vista has that file. The term that escaped me earlier was "superscript".....the raised character like that in a power (3²) which incidently is ALT 0178 for the power ². Learn something NEW everyday.

edit...I see where reible got the "superscript" term correct. I was behind in reading all the posts here when I replied.

Correct but the raised portion is technically called a "superscripted exponent".

Make a triangle (right triangle) from a piece of wood and use it because you don't have reible's plastic triangle.

But, maybe we should get bust making serious sawdust. That would be novel.

I don't know....maybe I'm brain damaged. I still don't get it AND I still don't see how Ed (reible) is in this. I don't even know what his plastic triangle is. Last I saw, it was brass. And no, I'm not putting you on. You know me......I never kid!

Take baby steps with me and I know that I'll get it eventually.

Forget about the circle part. He merely said(not in so many words) that 345 is a way to make a right triangle from scratch(material from the scrap pile). I also initially let the circle part get in the way of 'figgering it out'!:D
