NAME

6       Numeric limits -

Detailed Description

9       Some compilers do not give an implementation of <limits> yet. For the
10       code to be portable these macros should be used instead of the
11       corresponding method of std::numeric_limits or the corresponding macro
12       defined in <limits.h>.
