Sorry, I poorly formulated the question.

When I use 'stairs', initially tics look well.

When afterwards I zoom around, say, y=1, for a time being the ticks look OK, e.g.
0.99, 1, 1.01; 0.9998, 1, 1.0002; 0.999995, 1, 1.0001 - this one, by the way, shows some
kind of rounding asymmetry; then just 1, 1, 1, i.e. no fractional part.

Probably 'gnuplot' recalculates tics values when zooming is performed, and AFAIK 'gnuplot' uses 
single rather than double precision math.

But I wanted to make sure this phenomenon/problem does not come from 'octave'.

Thanks,
  Sergei.
