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.

The maximum number of digits and bits allocated for an unsigned long double in C++ varies depending on the specific compiler and system architecture being used. However, in general, the maximum number of digits for an unsigned long double is approximately 19 and the maximum number of bits is typically 64. This is due to the fact that an unsigned long double is typically represented using a 64-bit floating-point format, allowing for a maximum of 2^64 possible values. However, the exact number of digits and bits may differ slightly depending on the specific implementation. It is important for programmers to be aware of these limitations when working with unsigned long doubles in C++.
