Otherwise 'partial' has an error that is too large when you pass it to
the ln() function. Since decimal mostly follows IEEE 754 with arbitrary
precision extensions, it cannot behave differently.

Did you profile this? I did, and it still adds 22% to the runtime.

Try the patch from http://bugs.python.org/issue10547 or use an svn checkout.
The patch didn't make it into 2.7.1.

I think asking for strictly bounded resource usage is reasonable. In cdecimal
there is a switch to turn off correct rounding for exp() and log().

lts have to be weeded out before
attempting the correction loop for correct rounding, and this is
complicated.
For example, in decimal this expression takes a long time (in cdecimal
the power function is not correctly rounded):

The module is correct. Printing without exponent follows the same rules
as to-scientific-string:
"If the exponent is less than or equal to zero and the adjusted exponent
is greater than or equal to -6,
c = Decimal(str(random.uniform(100, 5000))).quantize(Decimal('0.01'))
var = Decimal('8.314').quantize(Decimal('0.01'))
# calc d
d = (a * b)/ (c * var)
if ((c*var*d) / b).quantize(Decimal('0.01')) != a:
print a, (c*var*d) / b

d = (a * b)/ (c * var)
d = Decimal(d).quantize(Decimal('0.01'))
By quantizing d, the above equality does not hold any l
tly good version numbers. If I don't
