Long double type in ROOT

Hello there.
Is long double type supported by all modules of ROOT, not only CINT?
What is the precision of this type (number of digits) and the range of this type If that is the case?

Thank you for future reply,

Sergij Begun.

No, only CINT supports long double. Not yet mature and stable with the compilers.
