When your calculator says 1.638617746E13 what is the real number?

Answer 1

The answer seems 16386177460000, because of: 1,638617746*10000000000000=16386177460000 (can you read this number? :).

But in fact this may not be true. It may be any number between 16386177460000 and 16386177464999. The reason is that your result is, most probably, approximate, e.g. not exact. It seems that you have 10-digit calculator. It means that it can store only 10 digits of result of each operation.


If you need an exact result then try to recalculate using at least 14-digits calculator or software calculator.
