I, too, have been told that "and" is to be used only for fractions, i.e
"1,234,567" is "one million, two hundred thirty-four thousand, five hundred
sixty seven", and "12 1/2" is "twelve and one half", and "12.34" should
technically be "twelve and thirty-four hundredths" - this last one is now
fairly rare, though, so we say "twelve point three four".
I, personally, find it absolutely fine to use "and" for separating numbers.
The way I prefer, and which I find the "most correct", is to include an
"and" if and only if anywhere between two non-zero digits does it cross from
the hundreds place to the tens place, or if it is directly from a 100*10^3n
place to a 10*10^3n place. For instance:
1,234 = One thousand, two hundred and thirty four
1,200 = One thousand, two hundred
1,004 = One thousand and four
1,000,394 = One million, three hundred and ninety-four
1,394,000 = One million, three hundred and ninety-four thousand
1,300,000 = One million, three hundred thousand
1,300,004 = One million, three hundred thousand and four
1,300,400 = One million, three hundred thousand, four hundred
This is just how I perceive it, of course...
~6 out of 5 statisticians say that the
number of statistics that either make
no sense or use ridiculous timescales
at all has dropped over 164% in the
last 5.62474396842 years.
