Declaring unsigned doubles??

[danielmarc]

Hi, I was wondering if you can declare double integers as unsigned. I'm writing a program that can not accept negative prices and the prices declared are double. I then test the input with the following...If this isn't possibe what would be a way to test that only positive values were entered. Thanks for any help.

unsigned double single, half, full;

cin >> single >> half >> full;

if(!cin.eof() && cin.good()){
 call...member function
}
else
{
cout << "Invalid price entered"
}

No, you have to test for negative values yourself. Sorry.

if(single < 0 || half < 0 || full < 0)
cout << "Invalid price";
