Excellent, that's exactly what I wanted to know.
So I would expect the relative error for those operations to be equal to 1
machine epsilon.

Am I right? Could you expose those as readonly through a const accessor
methods?
I need this functionality to be able to compare two floating point values
within specified ulp range (units in the last place).
