Detailed Description

template<class dst_type, class src_type, bool need_rounding = (std::numeric_limits<dst_type>::is_integer && !std::numeric_limits<src_type>::is_integer)>
struct round_helper< dst_type, src_type, need_rounding >

Helper struct to handle rounding between different types.

Note that we aren't worried about clamping here, that is handled separately by convert_helper (see below). We have different specializations of round_helper depending on whether the src and dest types are integral or floating-point. The only case where we have to do any actual rounding is when we're going from floating->integral.
