ReplyDeleteInteresting, result has a rounding error which forces to prints 'WHAT!!!!!!!!'. Decimal data type solves the problem.
ReplyDeletedouble x = Convert.ToDouble(7);
double y = Convert.ToDouble(5.3);
Decimal result = Convert.ToDecimal(x - y);
if (result == Convert.ToDecimal(1.7))
Console.WriteLine("No Bug");
else
Console.WriteLine("WHAT!!!!!!!!");
Console.ReadLine();

ReplyDeleteNever read it actually :$
ReplyDeleteHehe, there's still time ;)
ReplyDeleteErm, if you don't understand this then I don't think you should be blogging about programming.
