Can store a number twice as large as an int
WebSep 19, 2008 · To get max value you actually have to calculate the sum of 2^n with n from 0 to 31 or simpler 2^32 - 1 and you'll get '4294967295' as max for unsigned int, one less than anticipated. Now do the same with 2^31 - 1 for signed int and you'll get 2,147,483,647. WebValues of intermediate multiplication typically need twice the number of bits as inputs. // Example int foo(int a, int b, int carry, int rem) { int2x c; // Some type that is twice as wide at `int` c = (int2x)a * b + carry; return (int) (c % rem); } ...
