Mauricio de Alencar added the comment:
I propose then to create a context setting that switches between the current
textual representation of a Decimal and one that is "right zeros padded" up to
context precision.
Such that the line:
print(Context(prec=4, precise_repr=True).create_decimal_from_float(1.))
would output "1.000"
I post bellow a workaround for getting the result I expect just in case there
is anybody else with similar expectations.
from decimal import Context
def dec(num, prec):
return Context(prec=prec).create_decimal('{{:.{:d}e}}'.format(prec -
1).format(num))
Thanks for you attention.
