 Hi,
I wrote a test a program in order to see how djgpp will display a float
and was puzzled by the following:

#include <iomanip.h>
#include <iostream.h>
int main()
{
 cout << setprecision(25);
 double test = 37000.95000;
 cout << test;
 return 0;
}

Output : 37000.94999999999708961695
Can anybody explain why it outputs something so incorrect? Also, I
compiled this under other compiler and it worked ok -- the other
compiler displayed 37000.95
