If the OS different means the range of the datatype is also different?

I too think that it is -1.7e4932 to +1.7e4932.

Can someone explain how it comes 80 bits?

Is their any logic to find the value?

Long means 4 bytes.
Double means 8 bytes.

How long double 10 bytes?

The long double default range is same as the the double from 1.7E-308 to 1.7E+308.

But the long double data type is system(Processor, ABI, compiler)dependent and so its range varies accordingly.

You can also check the long double range with the function std::numeric_limits<long double>::min and std::numeric_limits<long double>::max.
