My preference is use the hex format throughout, so it hasn't been a priority and isn't likely to become one.

Long double presents special problems because it's not portable across machines, or across compilers in some cases.  In some environments it is the same as double.  So we can't assume host long double == target long double, or that host long double is big enough to hold a target long double, which in effect means we can't use host long double at all.  That makes doing conversions tricky, though not impossible.
