How do I prevent scientific notation when outputting decimal as a string?

When I try to convert a decimal.Decimal to a string, sometimes Python will output scientific notation (e.g. "123E-2").

>>> from decimal import Decimal
>>> str(Decimal('0.00'))
'0.00'
>>> str(Decimal('0.0000000'))
'0E-7'

How can I ensure the output is always in decimal notation (e.g. "1.23")?

Try setting the context `getcontext().prec = 28` – drum Jul 29 '20 at 23:27

You can use string formatting. f-string `f"{Decimal('0.0000000'):f}"` or `"{:f}".format(Decimal('0.0000000'))` – jakub Jul 29 '20 at 23:31
