Defines
#define	__EGlpNumAllocArray(__type, __size)
	Allocate an array of a given type and store (sizeof(size_t) bytes before the actual array) the size of the allocated array.
#define	__EGlpNumArraySize(__array)
	Given an array allocated with __EGlpNumAllocArray, return the size of the given array, if the array is null, return zero.
#define	__EGlpNumFreeArray(__array)
	, given an array allocated by __EGlpNumAllocArray, free the allocated memory.
#define	EGLPNUM_DEBUGL   100
	Debugging verbosity messages deped on the value of DEBUG (defined in eg_configure.h) and on the value of EGLPNUM_DEBUGL macro defined here.
#define	EGlpNumExit   EGlpNumClear
	provided for backwards compatibility
Number Types Definitions:
Define (as its name suggest) an internal identifier for the given type. this definitions are provided to select different types of data at compile time, thus allowing us to provide limited template support.
#define	DBL_TYPE   0
#define	FLT_TYPE   1
#define	INT_TYPE   2
#define	FP10_TYPE   3
#define	FP20_TYPE   4
#define	FP28_TYPE   5
#define	FP25_TYPE   6
#define	GNU_MP_Z   8
#define	GNU_MP_Q   9
#define	GNU_MP_F   10
#define	LDBL_TYPE   11
#define	LLINT_TYPE   12
#define	FLOAT128_TYPE   13
#define	INT32_TYPE   14
Functions
void	EGlpNumClear (void)
	This function must be called at the end of the program to free all internal data used in the EGlpNum_t structures, once this function is called any operation on EGlpNum_t types may fail.
void	EGlpNumStart (void)
	type-dependant constants and helper numbers
Variables
int	__EGlpNum_setup
	indicate if the global data needed for EGlpNum has been initialized, if zero, initialization routine should be called. This is provided to allow syncronization between libraries
