>>> x = Decimal(1000)
>>> y = Decimal(.005)
>>> x * y
Decimal('5.000000000000000104083408559')
I expected the result to be just 5
>>> a = 1000
>>> b = .005
>>> a * b
5.0
Above is what I expected.
====
The original intention is to divide a DecimalField from Django. Should I convert the Decimal value to float instead? For me to expect accurate resuls?
Pass it as a string:
>>> x = Decimal(1000)
>>> y = Decimal(".005")
>>> x * y
Decimal('5.000')
The issue is converting some floats into decimal. Starting with a string wouldn't be an issue.
As for your question: you should do the operations on a Decimal for it to be accurate.
