WebMost modern compilers provide built-in support for 64-bit data types. These data types are usually stored as two 32-bit integers in memory, and the compiler generates special code when arithmetic operations are performed on them. The following sections describe how the common arithmetic functions are performed on such data types. Addition WebMar 8, 2016 · Mathematically, it is equivalent to: a * (b / 2^32) You see b can be an integer but because it is divided by 2^32, you get a division. However the order of operations can be like this: (a*b) / 2^32. The last division/bit shift isn't even needed since that simply means the 'edx' part of the edx:eax composite result. easy chislic recipe
