That's just how the number is formatted for output by default. It has
nothing to do with how the number is handled in memory. You can
prevent it from outputting scientific notation using the 'f' format
specifier. Pick whichever example best suits your use.
>>> num = 12345678901234567890.
>>> print(num)
1.2345678901234567e+19
>>> print('%f' % num) # Using percent formatting
12345678901234567168.000000
>>> print('{:f}'.format(num)) # Using the str.format method
12345678901234567168.000000
>>> print(format(num, 'f')) # Using the format builtin
12345678901234567168.000000
Now, if you're working with very long floats then you're probably also
running into precision issues, as you can see in the examples above.
If the precision is important to you, then you may want to consider
using decimals instead of floats.
