Some compilers do not give an implementation of <limits>
yet. For the code to be portable these macros should be used instead of the corresponding method of std::numeric_limits
or the corresponding macro defined in <limits.h>
.
#define QL_MIN_INTEGER ((std::numeric_limits<QL_INTEGER>::min)()) |
Defines the value of the largest representable negative integer value
#define QL_MAX_INTEGER ((std::numeric_limits<QL_INTEGER>::max)()) |
Defines the value of the largest representable integer value
#define QL_MIN_REAL -((std::numeric_limits<QL_REAL>::max)()) |
Defines the value of the largest representable negative floating-point value
#define QL_MIN_POSITIVE_REAL ((std::numeric_limits<QL_REAL>::min)()) |
Defines the value of the smallest representable positive double value
#define QL_MAX_REAL ((std::numeric_limits<QL_REAL>::max)()) |
Defines the value of the largest representable floating-point value
#define QL_EPSILON ((std::numeric_limits<QL_REAL>::epsilon)()) |
Defines the machine precision for operations over doubles
