Changes in the value of int and uint during conversion

Int type data is converted to uint type: Because Int Is a signed type, when int is a positive number, int type data is converted to uint without changing. When int is a negative number and INT type data is converted to uint type, the value changes. However, the conversion process does not remove the previous negative number, for example, int A =-1; uint B = (uint) A; then the result of B is not 1; but 4294967295; we know that data stored in the computer is stored by the complement code. The Int size is 4 bytes, that is, 32 bits, and the first bits are the symbol bits; the size of the uint is also 4 bytes, 32 bits, but no symbol bit. If int A =-1, the complement code is stored in the computer: 1111 1111 1111 1111; the first digit is the symbol bit. Run uint B = (uint) A. when the data is converted to the uint type, the bucket still stores the complement code: 1111 1111 1111 1111; no sign bit. Then the value is 4294967295. Program : Static void main (string [] ARGs) {// calculate the maximum and minimum int A = 1, sum = 0; For (INT I = 0; I <= 30; I ++) {sum + = A; A * = 2;} console. writeline ("the maximum value of int type is:" + sum); // 0111 1111 1111 1111 2147483647 the result is sum ++; console. writeline ("the minimum value of the int type is:" + sum); // 1000 0000 0000 0000 2147483648 result is-} This article is from the csdn blog.
