{Code} Addition using bitwise operations + Multiplication using shift & add {Code}

Question

Friends check out my new code, which add two number without using Arithmetical operator, increment or decrement, or testing if x < y.

I don't have try-catch expression for negative integer and floating point values but will add later.

The only way I can improve is through your comments, so please give your valuable suggestion.
