Casting to integer (Int32) drops the fractional part of your number… int number = (Int32) 3.14159; // value of number will be 3 (not 3.14159) // Do this instead double c = Math.Sqrt(c2); // will give you the result you want output.Text = Convert.ToString(c); solved C# – Math.Sqrt() returning decimals
This turned out to be either a bug in the core library or a very misguided documentation, depending on the perspective (issue #29850). The behavior of the function unsafe_convert changed from version 0.4 to 0.5, in a way that makes it more flexible than what is currently suggested. According to this commit, unsafe_convert changed from … Read more
There are implicit and explicit conversions. A cast is always an explicit conversion and uses the (type) cast operator. C has quite decent type safety when it comes to pointers. Apart from the special case of null pointer conversions, the only implicit pointer conversion allowed is between an object pointer and a pointer to void. … Read more
The question boils down to: If I write this: int x = ‘ÿ’; x will be -1 but I’d like it to be 255. It’s -1 because ‘ÿ’ is a char of value 0xff. But as char is signed on your platform, sign extension takes place when you assign it to an int. The solution … Read more
