OK, so I have a sudden urge to calculate really big numbers using Python. I've googled that python has no limit on the amount of characters that the number can you show. For example if I execute this:
import decimal
from decimal import Decimal
print(Decimal(641599888**5)**7)
The console will print out:
1.795766151434572597248927442E+308
If I again, run that through the print(Decimal...
print(Decimal(1.795766151434572597248927442E+308))
I get a massive number, with 309 digits:
179576615143457258700075088916205475704544728014348494378770201678625049728092745025740069670306256620000514266741755110731581159875713825371899514543785615348608901625672610723539647663835386726798483725257724640018240253857448988824387413636072364105453081728316837991208604405084707759438827801454827274240
Although, if I try and do the same with a higher power and do the same 2-step process, my result in the console will be:
Infinity
How can I make it that Python3 will not spit out infinity, but the whole massive number with ALL (say 10,000) it's digits? Is there a way to turn off getting "Infinity"?
You can convert your integer to a string and then print it:
>>> print(str(641599888**400))

Note that this will not work when precision is required (i.e. floating point), since some kind of rounding is done here.
Edit thanks to Mark Dickinson:
conversion to str is not required
