Well, the number of atoms|molecules in one mole of gas at standard 
temperature 
and pressure is actually more precisely   6.02214129x10^23  (depending on 
who you talk to)

However, back in the day--- Chem 201 UMKC 1975,  I set the cursor of my 
dual base 
log log slide rule (Pickett)  just to the right of  6  and then kept track 
of the decimal place
myself in my notebook...    ;-)

... but now I have python:   whoohoo!

>>> d(6.02214129e23)
Decimal('6.02214129E+23')
>>> av=d(6.02214129e23)
>>> int(av)
602214129000000000000000       <=====    yousah like this better?
>>> 

Cheers
