ExcelBanter - 99999999999990 why does the 0 pop up at the end of this string

Excel only provides for 15 significant digits as a floating point number.
Which is a lot more accuracy than is needed for most fields of science,
certainly sufficient rocket science.. .

If you want a "number" with 16 characters, it is very unlikely that you
should ever have considered it to be a number (to be used arithmetically),
but rather it is an identification "number" and should have been
formatted as text.

This *problem* usually crops up when people enter Credit Card Numbers
into Excel and end up with invalid numbers, as most credit cards are 16
digits.
