Can you re-explain please.
As envisaged at present, only the value of numeric_limits<>::digits
is used to chose the right interval constants.
If this value is wrong tough.
Or not defined then won't compile.
This should make it work correctly even if long double is 53, 56, 64, 106,
112, 113, or 128 (?)
Or an I missing something?
