    about std::numeric_limits?

    hi,guys
    i used the std::numeric_limits<double>::max();,but visual C++ 6.0 reported the error C2589: '(' : illegal token on right side of '::'
    G:\MY program\temp\test1\test1.cpp(12) : error C2143: syntax error : missing ';' before '::'

    anyone know if visual C++ 6.0 support std::numeric_limits?

    thanks in advance

    Did you include <limits> and specifies the namespace, like "using namespace std;"

    I thing its because
    'max' is already defined as a macro.

    try this before your use of
    std::numeric_limits<double>::max()

    #ifdef max
    #undef max
    #endif

    and see if it works

    Greetings,
