MATLAB: IF – Same comparison, different results

if statementMATLAB

I have this If statement
if abs(DespSubSis(1) - Carga(1)) > abs(PTIE)
    k = k + 1;
    flag = 1;
elseif abs(DespSubSis(2) - Carga(2)) > abs(PTIE)
    k = k + 1;
    flag = 1;
end
being
DespSubSis =  700.0000  700.0000
Carga =   850   550
PTIE = 150
The first If returns 0, but the second 1.
Both should returns 0 since It's false 150 > 150.
What's wrong? 🙁

Your values are not exact integers. You should display
DespSubSis - fix(DespSubSis)
Carga - fix(Carga)
You will find something non-zero.
