PrimeET
an Excel^{TM} spreadsheet
by Joe Monzo
PrimeET is a handy little spreadsheet that allows you to create a table of primefactors and their exponents, and input an n value for an ndegree ET.
If your computer can read Excel^{TM}, download it here
The program calculates:
It's set up with primes of 2, 3, 5, 7, 11, and 13, but they may be changed to any number at all, including nonprime oddfactors, integerfactors, pi ...anything.
The ET I have in there is my current object of study, 144eq. You may enter any number at all  I don't know up to what limit, but ***************
If 2 is used as a factor, it allows you to:
As an example of the latter, to enter the 12eq 'perfect 5th', just enter in the '2' column*************:
=7/12
Any plain number (including decimals) can just be entered as is, but for any exponent that uses a calculation (like the ET shown above), make sure to enter the equal sign first, otherwise Excel will think you're trying to enter a date when you enter the slash.
One glitch is that the 'ratio' column will show a fractional ratio for an ET or other 'irrational' value.
I formatted it that way purposely so that it would convert the primefactors & exponents into ratios that look the way most people who use them are used to seeing them.
It's easily changed from the menu choice FormatCells, or with a rightclick on the mouse, with the same choice on the popup menu. It may be formatted as a decimal or a variety of other ways.
Feedback welcome. Enjoy!
