Using bitwise OR 0 to floor a number
...
Javascript represents Number as Double Precision 64-bit Floating numbers.
Math.floor works with this in mind.
Bitwise operations work in 32bit signed integers. 32bit signed integers use first bit as negative signifier and the other 31 bits are the number. Because of this,...
