Ok thats a diff thing but what i posted is somewhat different actually what happen is that .5 can be represented completely in binary form and the same case with 1.0 and .25 , .125 also but when we talk about .7 then it cant be represented in binary precisely even we upgrade it to double. thats why a==.5? works but not c==.7?
