How can I enter longdouble (float96) literals into my python/numpy
programs? In C, I would postfix such numbers with 'L', but this gives
a SyntaxError in python.

Hello list,
When I do 10**-2, Python nicely returns 0.02
But with numpy (version 1.3.0), I get zero:
In [492]: 10**array([-2])
Out[492]: array([0])
Is this the intended behavior?
Thanks, Mark

I think the problem is that array([-2]) is an array of integers, so the
result is also an array of integers. It works fine with array([-2.0]).

I understand why numpy does it, but even Python itself gives 10**-2 = 0.01.
So I am wondering whether this is the intended behavior of numpy. I don't
really think so, but I may be wrong.

The MSVC compilers don't support extended precision, or rather, long doubles
are the same as doubles. I don't know what other compilers on windows do.
