as a rule of thumb "Never Test Doubles For Equality" ... due to the representation errors of course instead you should do that : 

if(fabs(dist1+dist2 - dist) <= EPS){
// do something
}

where EPS is a very small value for allowed error .. maybe something like 1e-9

I would also say think twice before you use double comparison.Do you really need it?

In most of them you won't, but if you do use as rawbear1826 described.
