Effect on decimal values rounded to the nearest binary representable power of ten precision?

Actually i have some property in my chart control which create auto scale and enable setting that decimal values should be rounded to the nearest binary representable power of ten precision.

If i have following values then what will be effect on the values if they are as:

326317120.7
336446588.6
328645939.5
328064491.6
323417873.9


Or

.44
.43
.23
.54


etc.

What is following line means regarding values conversion:

"decimal values should be rounded to the nearest binary representable power of ten precision"

and how is it effect the values if we apply on some values??

The phrase you have put in quotes does not follow the rules of English sentence construction, so its interpretation is highly unclear. Are you able to plug some values into your "chart control" (whatever that is) and see what comes out? Maybe if we saw the effect on some values we could reverse engineer the thing and figure out what that quotation means. – Gerry Myerson Jun 25 '12 at 12:49

Are you able to plug some values into your chart control to see what comes out? I don't think you understood my comment at all. – Gerry Myerson Jun 25 '12 at 13:15
Thanks for you comment..I have checked that but not able to figure out that what is changing.. just small example of conversion i need at this time so that i can understand that what it will do... – Niranjan Kala Jun 25 '12 at 15:30
"I have checked that" - does that mean you have plugged some values in and you have seen what comes out? Maybe if you share those input-output pairs with us we'll be able to see what's going on. – Gerry Myerson Jun 26 '12 at 5:59
