Re: Unexpected division quotient

"Double-precision floating-point is generally
accurate to 15 digits of precision."
http://publib.boulder.ibm.com/infocenter/iseries/v7r1m0/index.jsp?topic=%2Fdb2%2Frbafzch2num.htm

Well, virtually all double-precision floating point throughout
computing is IEEE 754:

http://en.wikipedia.org/wiki/IEEE_floating_point

The spec, if followed exactly, guarantees 15 digits of precision, with
the 16th digit usually being accurate as well. Note that this does
NOT refer to digits "to the right of the decimal point", unless you
are talking about normalized scientific notation.
