It's not as easy as it sounds. Basically I can move $A$ and check the distance to $B$. However there is a $\pm0.015$ error range , in other words if the real distance is $0.29$, it will get rounded to $0.3$. So the possible values are : $0.03$, $0.06$, $0.09$ and so on
I tried drawing two circles and finding the intersection but the thing in the square root is negative. I assume this is because of the rounding - the circles don't actually overlap.
Is there a method to find the coords of $B$ given the error margin? (note the coords need to be accurate in a circle of $0.05$ around the real coords) I can move $A$ at any point I want and get the rounded distance - can I increment until the value changes and derive the actual real distance from that?
