[Boost-users] [Multiprecision] Get mantissa of a float

Hello, I'm new to the Multiprecision library, and am trying to extract the mantissa from a float. Using cpp_bin_float, it's easy to get the exponent, but how can I get the mantissa in a normalized form (1.xxxxxxxxxx)? I tried messing with the limbs, they contain large powers of two, but I couldn't interpret that. Thank you very much, Leo Y.
