16 Language support library [language.support]

16.3 Implementation properties [support.limits]

16.3.1 General [support.limits.general]

The headers <limits>, <climits>, and <cfloat> supply characteristics of implementation-dependent arithmetic types ([basic.fundamental]).
The header <version> supplies implementation-dependent information about the C++ standard library (e.g., version number and release date).
The macros in Table 35 are defined after inclusion of the header <version> or one of the corresponding headers specified in the table.
[Note
:
Future versions of this International Standard might replace the values of these macros with greater values.
