Preventing engineering notation in Python's decimal

Question

I use decimal objects whose values get close to zero. By default, a statement such as

print (decimal.Decimal('0.00000000004') / decimal.Decimal('2'))

will output 2E-11. How do I prevent this from happening and get 0.00000000002 instead?

`'{0:f}'.format(decimal.Decimal('0.00000000004') / decimal.Decimal('2'))` — suhailvs, Jul 08 '14 at 09:09

To get the decimal point You need to format the print

print "{:.11f}".format(decimal.Decimal('0.00000000004') / decimal.Decimal('2'))

num = decimal.Decimal('0.00000000004') / decimal.Decimal('2')
print '{:.50f}'.format(num)
print '{:.2f}'.format(num)
