The problem with this technique is that it will not work for large numbers (in my build of node, for example, the largest number it will work with is 2^31 - 1: (Math.pow(2, 31) - 0.1) // base number 2147483647.9 ~~(Math.pow(2, 31) - 0.1) // works! 2147483647 (Math.pow(2, 31) + 0.1) // base number 2147483648.1 ~~(Math.pow(2, 31) + 0.1) // doesn't work! -2147483648
