Re: [U2] [UD] Precision

Google on "Bankers Rounding" on almost any computer news group and you'll 
find what you need.  There will always be some error because some numbers 
just don't convert back and forth from rational to decimal without error. 
And of course there are 52.1667 weeks in a year so there's a source of error 
in itself.  The best way to reduce the error is to do only one conversion 
between rational and decimal for each paycheck but that's not always 
practical.  There are stories of early day programmers doing quite well for 
themselves by crediting the cumulative round error to their own accounts. 
Some of the stories may even be true :)

You're counting weeks, not months.  A month does not divide by two
equally.  If you are getting two paychecks a month, then you get a
paycheck for (approximately) 15.2 days worth of work.  If you get a
paycheck every other week, you are getting it for 14 days work, exactly.
