Hi Michael, yep, darn right, half the people in

the world (including me!) have been rounding wrongly

their entire lives. Very scary. There is and can only

be one correct way of rounding decimal numbers...

Here is an example, assuming rounding to 3 decimal

places, that is 1000 combinations, from 000 to 999.

000 to 499 (first half), 500 to 999 (second half).

There are the first 500 combinations in the first

half, and the second 500 combination in the second

half.

All my life I have been rounding at 555, under the

false impression that 5 is "half way" in decimal

terms... Wow.

I asked my 26 yr old science-degreed girlfriend how

to round and she looked at me like I was stupid.

"5 or more, round up". She was taught correctly.

Now I'm wondering if it is mainly us old-timers

from the dawn of pocket calculators age that were

taught wrong?? Any thoughts, older people??

:o)
