Detailed Description

Basic types used by ROOT and required by TInterpreter.

It ensures a portable fixed data type size across systems, since in the early days, sizeof(int) could be 2 or 4 depending on the architecture.

Deprecated: For future designs, unless for very specific needs, consider using instead standard fixed-width classes from <cstdint> such as std::int16_t, std::int32_t or from <cstdfloat> for floating types.

Warning: Long_t has not the same width across platforms, so it should be avoided if portability is envisioned. Also derived classes such as TArrayL. Use instead Long64_t or TArrayL64, or std::int64_t. Likewise with ULong_t.; In some architectures, std::int64_t may have a different underlying data type (long vs int) than in others and may lead to a different StreamerInfo than in others, thus it might be convenient to use (U)Long64_t instead. Hence, full fledge embrace of the std::types is actually waiting on ROOT I/O to be extended to support them explicitly.
