Subject: [Boost-users] [Random] uniform_01

Hi,
I was looking at the docs for the uniform_01 distribution:
http://www.boost.org/doc/libs/1_39_0/libs/random/random-distributions.html#uniform_01
I read the following note
"Note: The current implementation is buggy, because it may not fill all
of the mantissa with random bits."
I do not understand the problem. I looked at the code, which does what
I expect. Why is it a problem if some of the mantissa bits are not
'random'? As I understand the requirement is the real numbers are
uniformly distributed; the bit patterns should not matter provided they
represent numbers with the right mathematical properties.
Thanks
Robert Patterson
