I assume, the typedef doesn't value the "hooked" malloc, thus,
I recommend:
long double *big_double;
big_double = (long double *) malloc(2*sizeof(long double));

Dear Steven,
Sorry, don't mean to nitpick.

It's fine, as it is. Typedefs most often reside in header files,
although, they can be used in the main file without suffer.
If you ever should get bored, read the Perl Sources.

Sorry my C is barely Novice.
Where can I put this snippet in my C subroutine?
like this:

Fine, it was even 2 Bytes bigger than excepted.
typedef (malloc(2*sizeof(long double))) Big_Double;
Big_Double var;
var should measure 24 bytes in size, which should suffice;
if not, increment the factor

Another solution would be, dynamically allocating memory:
long double var;
var = (long double *) malloc(2*sizeof(long double)

What does printf("%i\n", sizeof(long double)); tell you?
The byte sizes of variable types can vary from platform to platform.

Hi Zentara,
Thanks for the reply.

It worked, but still limited. It overflowed when N>500.
Most of the value of N, I use are around 1000-2000.

Hi,
I have the following code that uses Inline::C to compute factorial.
The problem is that whenever I use large N (>30) it began to return "INF".
I thougtht my C implementation already cater large number by using "float"?
Additionally I have already added Math::Pari as an attempt to solve
the prob
