The distinction between signed and unsigned numbers in the assembly and CF,OF flag bits first, there is only one standard. First of all need to know that the computer to the value of the storage of a complementary form of storage, one avoids the

This problem is easy to understand. However, if you think deeply, there are some things.Next I will try to extend this item to a bit more in-depth. I. There is only one standard! At the Assembly language level, when declaring variables, there is no

1 int i=3; 2 cout1;ask what the result is. First reaction:-3. But the result does not seem like this, wrote a program, ran a bit, found that:4294967293. 1) on a 32-bit machine, the int and unsigned int are 32 bits (4 bytes). 2) enum will be

PHP converts a signed integer to an unsigned integer. This article describes how to convert signed integers to unsigned integers in PHP. the conversion method is simple, this document describes how to convert signed integers to unsigned integers in

Previous blog We have explained the representation of integers in computers, including unsigned and complementary codes, and the conversion between them, which is a very important point of knowledge for individuals. In this blog we will introduce
