Hi
 
double type has 64 bit width and can hold number as small as 1e-308.
i want a data type even smaller than double.
 
i read in help that long double has 80 bit width and can store as small as 1e-4000, but in VC, when i declare a variable with this type, it threats as double type.
 
where is the problem?
 
thanks
