suppose there is an ODE function `F`

solved by `NDSolve`

and the solution of this function is in the range [-40 : 34]. Only, I need where the `F==0`

, or the value of `F`

in the interval between [-1,1]. How can I achieve this by using table:

`Table[If[F <= 10^-2, Print@F, Return["Exit", Table]];, {x, 3.2, 3.5, 0.01}, {y, 3.2, 3.5,0.01}]`

Using the above code gives me all the negative region. So, I am trying to catch the value of function `F`

when it close to zero or zero, and prints it if the following condition is satisfied: a) The `F`

has a value close to zero. Thanks in advance for your time, and sorry if this is simple, I couldn’t find a solution within this site.
