[RESOLVED] Numeric Limits

Does c# have anything like std::numeric_limits in c++?

You should perhaps explain what std::numeric_limits is or does, for those of us who know C# but not C++ (or at least haven't touched C++ for years :)).

It defines the max and min numbers for the machine.

Code:

---

const int    MaxInt    = (std::numeric_limits<int>::max)();
const double  MaxDouble = (std::numeric_limits<double>::max)();
const double  MinDouble = (std::numeric_limits<double>::min)();
const float  MaxFloat  = (std::numeric_limits<float>::max)();
const float  MinFloat  = (std::numeric_limits<float>::min)();

---

All the standard numeric types have static MinValue and MaxValue fields that return their minimum and maximum values:

Code:

---

const int    MaxInt    = int.MaxValue;
const double  MaxDouble = double.MaxValue;
const double  MinDouble = double.MinValue;
const float  MaxFloat  = float.MaxValue;
const float  MinFloat  = float.MinValue;

---

etc. There's no point declaring your own constants though. Just use those fields as and when required.

Thanks! I knew it would be something easy, but I couldn't find it in my beginning c# book.
