template<>

const float max_limit< float >

(

)

A small set of numeric limits routines, since gcc prior to 3.x doesn't have numeric_limits.

Return the largest possible number that a float may hold.

Find the maximum limit for a type, equivalent to std::numeric_limits<T>.max() for systems that don't have the limits c++ header file. Find the maximum limit for a type, equivalent to std::numeric_limits<T>.min() for systems that don't have the limits c++ header file. Return the largest possible number that a float may hold.

template<>

const double min_limit< double >

(

)

Return the smallest positive number that a double may hold.

Caveat: This is in contrast to other types, where min_limit<T>() will return either 0 or the largest possible negative number that the type may hold. If you are looking for the largest possible negative number for any given type, use lowest_value<T>() instead.
