Maximum Digits and Bits for C++ unsigned long double

[Deathfish]

in C++, how many digits and how many bits is the maximum allocated for unsigned long double?

 

[D H]

None. There is no such thing as an unsigned long double, at least not in the standard. If you have such a beast you are using a non-compliant C++ compiler.

 

[Deathfish]

ok so what's the maximum then...

and how does having a 32-bit or 64-bit OS affect this?

What's the maximum of what? I think that you are confusing two different types: unsigned long (or unsigned long int) and long double.

The first is an integer type and the second is a floating point type. The sizes of these types depends on your particular C++ implementation. You should have a header file named "limits.h" that will indicate the largest sizes of ints, long ints, floats, doubles, and so on.
