#define	devCreateMask(NBITS)   ((1<<(NBITS))-1)
	Create a bit mask for a given number of bits.
#define	devDigToNml(DIGITAL, NBITS)   (((double)(DIGITAL))/devCreateMask(NBITS))
	Normalize a raw integer value and convert it to type double.
#define	devNmlToDig(NORMAL, NBITS)   (((long)(NORMAL)) * devCreateMask(NBITS))
	Convert a normalized value to a raw integer.
Macros for pointer alignment
Warning Deprecated, we don't know of any code currently using these.
#define	devCreateAlignmentMask(CTYPE)   (sizeof(CTYPE)>sizeof(double)?sizeof(double)-1:sizeof(CTYPE)-1)
