WebMar 7, 2024 · Arithmetic operators. Returns the result of specific arithmetic operation. All built-in operators return values, and most user-defined overloads also return values so that the user-defined operators can be used in the same manner as the built-ins. However, in a user-defined operator overload, any type can be used as return type (including void ). WebAug 11, 2008 · An "arithmetic" shift leaves the original value in the leftmost bit. The difference becomes important when dealing with negative numbers.) When shifting an unsigned value, the >> operator in C is a logical shift. When shifting a signed value, the >> operator is an arithmetic shift. For example, assuming a 32 bit machine: WebMay 5, 2010 · Just as with decimal longhand division, the digits of the dividend are considered from most significant to least significant, one digit at a time. This is easily accomplished by a left shift in binary division.
