Widening unsigned integer multiply without setting flags. Multiplies EDX/RDX with r/m , then stores the low half of the multiplication result in ra and the high half in rb . If ra and rb specify the same register, only the high half of the result is stored.
Amiga software executable Hunk files running on Amiga classic 68000 machines all started with the hexadecimal number $000003f3, nicknamed the "Magic Cookie." In the Amiga, the only absolute address in the system is hex $0000 0004 (memory location 4), which contains the start location called SysBase, a pointer to exec.library, the so-called ...
010 Editor is a commercial hex editor and text editor for Microsoft Windows, Linux and macOS. Typically 010 Editor is used to edit text files, binary files, hard drives, processes, tagged data (e.g. XML, HTML), source code (e.g. C++, PHP, JavaScript), shell scripts (e.g. Bash, batch files), log files, etc. A large variety of binary data formats ...
In computer science, an integer literal is a kind of literal for an integer whose value is directly represented in source code.For example, in the assignment statement x = 1, the string 1 is an integer literal indicating the value 1, while in the statement x = 0x10 the string 0x10 is an integer literal indicating the value 16, which is represented by 10 in hexadecimal (indicated by the 0x prefix).
The number 4,294,967,295, equivalent to the hexadecimal value FFFFFFFF 16, is the maximum value for a 32-bit unsigned integer in computing. [6] It is therefore the maximum value for a variable declared as an unsigned integer (usually indicated by the unsigned codeword) in many programming languages running on modern computers.
For example, INT 13H will generate the 20th software interrupt (0x13 is nineteen (19) in hexadecimal notation, and the count starts at 0), causing the function pointed to by the 20th vector in the interrupt table to be executed. INT is widely used in real mode. In protected mode, INT is a privileged instruction. [1]
That is, the value of an octal "10" is the same as a decimal "8", an octal "20" is a decimal "16", and so on. In a hexadecimal system, there are 16 digits, 0 through 9 followed, by convention, with A through F. That is, a hexadecimal "10" is the same as a decimal "16" and a hexadecimal "20" is the same as a decimal "32".
("decaf bad") is often found in coding as an easily recognized magic number when hex dumping memory. 0xDEFEC8ED: 3741239533 ("defecated") is the magic number for OpenSolaris core dumps. [26] 0xD0D0CACA: 3503344330 ("doo-doo caca") is the uninitialized value of GPIO values on the Nvidia Tegra X1. [citation needed] 0xE011CFD0: 3759263696
