Methods of how C + + obtains numerical extremum

This article mainly introduces how C + + How to obtain numerical Extremum method, small series think very good, and now share to everyone, also for everyone to do a reference. Let's take a look at it with a little knitting.

Include <iostream> #include <limits>using namespace std, #define L_value (a) (cout<< (#a) << "is" << (a) <<endl) #define L_ADDR (a) printf ("%p\n", a) int main () {  l_value (numeric_limits<short>:: Max ());  L_value (Numeric_limits<int>::max ());  L_value (Numeric_limits<long>::max ());  L_value (Numeric_limits<float>::max ());  L_value (Numeric_limits<double>::max ());    GetChar ();  GetChar ();  return 0;}
