Here are a few points to note about the 32-bit signed integers used by JavaScript bitwise operators: The most significant (leftmost) bit is called the sign bit. The sign bit is always 0 for positive integers, and 1 for negative integers. WebMay 18, 2024 · Number (x), parseFloat (x) and +x will all give x as a floating-point number. parseInt (x) will give x as an integer. x 0 and x >> 0 will give x as a signed 32-bit integer. (In general, this applies to most bitwise operators.) x >>> 0 will give x as an unsigned 32-bit integer. I would recommend that you use Number, parseFloat or parseInt ...
