This is why every programmer needs to understand the modulo operator.
Or bitwise AND.
This is what I prefer too! I also some times prefer to use bitshift when it comes to division or multiplication of power of 2.
I would divide by two (floating point) and check the fractional part.
turns out that 2^53 + 1 is an even number
The article only covers unsigned 32-bit numbers, so floating point division would be fine.
