Subject: [boost] Floating point truncation bug in qi::float_

Hi I am using boost 1.4.1 Spirit::Qi.
I think we have a floating point truncation bug in the qi::float_ parser.
I attached a simple program to repro the bug.
Below are some examples of an input floating point gets truncated (=>) by
the qi::float_:
12312321421421 => 12312321720320.000000
123123214 => 123123216.000000
123233.4124 => 123233.406250
I don't see the same issue with the qi::double_.
Wondering if this is a known issue?
Regards,
HTan
