Yes. I made a typo, and will correct it. Thanks.
For testing halfway, a%b == b/2, or (a%b)*2 == b

I assume "overflow" meant lost of precision ?

This is one nice thing about binary math, *2 or /2, we do not lose precision.
Scaling just update the exponent, similar to *10 or /10 for decimal system.
