Are you sure that 8.575 isn't really 8.57499999 or something like 
that?  When I do

. set obs 1
obs was 0, now 1

. gen x = 8.575

. gen y = round(x, .01)

. list

     +--------------+
     |     x      y |
     |--------------|
  1. | 8.575   8.57 |
     +--------------+

Looking at the data in the data editor, I see

x = 8.5749998
y = 8.5699997
