The way you deal with it will depend on what you want to do.
If you want to see is something is "close enough to zero" you subtract
them and check the difference
if (Math.abs(i - 952.86)<=0.1){trace("close enough for me")}else
{trace("Not the same")};
if (Math.abs(i - 952.86)<=0.0000000001){trace("Really close ")}else
{trace("Not yet the same")};
If you use enough leading zeros you will get code that never evaluates
to true so do not get wild with leading zeros.
As long as you remember that numbers that are not explicitly cast as
integers have to be treated with care, you will be alright.
This problem has been around the computer world for the last 50 years
and will be around for some time to come, so we have to just deal with it.

How do you usually deal with the loss in precision (a bit oxymoron since
floating point can't be exactly represented) when converting a floating
point string to a number?
var s:String = "952.86";
var i:Number = parseFloat(s);
trace(i);
trace(i - 952.86); // Not zero!
