C++: get value for integral types?

Does anyone know whether it is possible to get a tuple's value as an
int, float, bool, etc. using the C++ postgresql library?

Getting floats as string representations (via char* GetValue(...)) of
the value is not acceptable! Using strings and streams to convert the
values to the corresponding integral type may cause problems!

Any ideas, workarounds? Is BinaryTuples really not implemnted yet?

thanks...
