How can I convert a signed integer into an unsigned integer?
The piece of code is like:-
int x = -24;
uint y = (uint) x;
Console.WriteLine("*****" + y + "********");
// o/p is *****4294967272********
Why this type of behavior in C#, Detailed elaboration would be helpful. Thankyou all.
Answer
Negative numbers (like -24) are represented as a binary complement, see
en.wikipedia.org/wiki/Two's_complement
for details. In your case
24 = 00000000000000000000000000011000
~24 = 11111111111111111111111111100111
~24 + 1 = 11111111111111111111111111101000 =
= 4294967272
When casting int to uint be careful, since -24 is beyond uint range (which [0..uint.MaxValue]) you can have OverflowException being thrown. A safier implementation is
int x = -24;
uint y = unchecked((uint) x); // do not throw OverflowException exception
