How to get fractional values from a vector

I am using glpk solver for getting the LP variable values of a minimization problem in xmin. xmin is a vector containing 0, 1 and some fractional values. then I want to get the fractional values among them.

    frac_value = find (xmin > 0 & xmin < 1)

    frac_value_xmin = xmin(frac_value)

frac_value should give me the positions of fractional values from xmin. frac_value_xmin should give me the values.

Where `xmin =`
`1.0000000000000000`
`1.0000000000000000`
`0.0000000000000000`
`-0.0000000000000000`

after the `find` operation it returns `frac_value = 3` and `frac_value_xmin = 2.4652e-32` where it suppose not to return anything. I tried with `frac_value = intersect(find(xmin>0), find(xmin<1))` which gave me same type of problem too. I have no idea why this is happening. Any help regarding this will be appreciated.
