negative int

Problem Description: When a file stream reads a hexadecimal file, it is often necessary to read some bytes out to parse the INT data that represents the size, and there may be negative numbers in the conversion process, and the good solution is to

Uint and INT are multiplied. If int is negative, the result is very large. Unsigned int leftval = 1; Int rightval =-1; Float result = leftval * rightval;   The result is: 4.29497e + 009. It is not the "-1" result you want.   However, if it is

1 ; int x =-2; For the above results theThere's a minus-complement problem and implicit type conversion between different types.First, the representation of negative numbers is the absolute value of the negative number of binary code

Analysis of conversion from negative to binary in JAVA, conversion from negative to binary in java I recently looked at the collection source code and found that ArrayDeque uses a large number of & Operations, which involves binary. I suddenly found

1, Decimal negative turn binary system Suppose there is a number of int type, and the value is 5, then we know that it is represented on the computer as: (because the int in Java is 4 bytes, so the high level needs to be 0 and 32 digits)00000000 0000

1. Convert negative decimal number to binary number Suppose there is an int type number with a value of 5, so we know that it is represented as: (because int in java is 4 bytes, so it needs to be supplemented with 0 at a high level, 32 digits)000000
