Suggestion box - more bitwise ops

I don't think we'll have these language primitive ops in the near future.... However, the logical operators or,and, and not are also bitwise operators.... So the operations you are asking for can be implemented in terms of those base bitwise operations.

Example:

    a% = 6
    b% = 10
    print "a = ";a% ;" b = "; b%

    bitwiseAnd% = a% and b%
    bitwiseOr% = a% or b%
    bitwiseXOr% = bitwiseOr% and not bitwiseAnd%

    print "a xor b  = "; bitwiseXOr%

    bitwiseLeftShift% = a% * 2

    print "a << 1 = "; bitwiseLeftShift%
    
    bitwiseRightShift% = a% / 2

    print "a >> 1 = "; bitwiseRightShift%

Understood about the xor, it just seems that since there are the bitwise operations for AND, OR, and NOT, an XOR would be trivial to add and complete the offering.

As for shift, left shifting is easy, because it's multiplication. Right shift is division, which results in a float. It's not as ideal. The following is what I have, and it works without division (which is key), but it's obviously nowhere near as fast as a native implementation would be:

function rshift(num as integer, n=1 as integer) as integer
        mult = 2^n
        sumand = 1
        total = 0
        for i = n to 31
                if (num and sumand * mult)
                        total = total + sumand
                end if
                sumand = sumand * 2
        end for

        return total
end function

That's why I used the '%' character at the end of all my variables. That forces the types to be integers, and then the division to be integer division rather than floating point.
