You don't say how you are observing this. Beware that some popular
applications (like Photoshop) don't display the full precision of
the underlying color values. They round to the nearest integer in
their readout. Underlying color values are almost certainly a minimum
of 8 bits (256 distinct levels), and might be more than this (16 bit
or floating point).
