crazydeveloper Javascript support Integer type?

JavaScript does not support an integer type. All numbers in JavaScript are stored in 64-bit floating point format i.e. double precision floating point. The bitwise operators that manipulate numbers at the bit level do not perform operations directly on this 64-bit floating-point representation. Instead, they coerce the numeric values to signed 32-bit integers, do the necessary operation, and again convert the result back to floating point format. This conversion has a performance impact.
