A field defined like this:
{{{
foo = models.DecimalField(max_digits=20, decimal_places=6)
}}}
When trying to set a float 0.2 it would give an error regarding the
maximum decimal places. That because the context that converts the float
to decimal only respect max_digits:
{{{
In [1]: import decimal
In [2]: c = decimal.Context(prec=20)
In [3]: c.create_decimal_from_float(0.2)
Out[3]: Decimal('0.20000000000000001110')
}}}
For floats django should probably round the value to the decimal_places
defined in the field.
