What does the number 1.26E-23 mean?
Is it a large or small number
It is a very very small number, very close to zero. I wonder if your real
question is: how do you avoid it?
If you are entering numeric strings longer than 15 digits (account numbers,
product serial numbers, etc.), you should enter them as text. Exactly how to
do that depends on how you are entering the data. If you entering them
manually, simply put an apostrophe (') in front of the numeric string.
If you see numbers of that form as a result of computation, you probably
should round the computation, either by using the ROUND function or by
setting the Precision As Displayed calculation option (Tools > Options >
Calculation in Excel 2003). I usually deprecate the use of PAD, however.
