Re: [Boost-users] [enable_if][type_traits] Overload resolution question

often as an optimization the code uses binary shifts to represent power of 2 multiply/divides. Going forward these divides need to work with both fixed and floating point types so f >> 1 needs to change to f / 2. Is it possible to create an overload for the / and * operators that determine if the operand is an integral constant and is a power of 2 and use a binary shift internally?

If, in the end, the thing you are shifting is an integer type, the compiler will do the '/ 2' => '>> 1' substitution for you. So don't worry about it. Thanks,
