The following example illustrates use of the bitwise NOT (~) operator on decimal numbers.
To keep the example simple, decimal number
3.5 will be used, cause of it's simple representation in binary format.
let number = 3.5; let complement = ~number;
Result of the
complement number equals to -4;

To simplify this, we can think of it as function
f(n) = -(integer(n)+1).
let a = ~-2.5; // a is now 1 let b = ~-1.5; // b is now 0 let c = ~0.5; // c is now -1 let d = ~1.5; // c is now -2 let e = ~2.5; // c is now -3
