Don't use max precision. PowerToy Calc etc don't work with system floats / doubles but alternative implementations.
float / double is always approximative.
float is usefull up to 5 - 7 decimals behind ., double logically the double of it.
so, everything after 0.707106781186547389 is pure approximative and can (and most likely will) be false
