In looking through paranoia.c to find out how to make a run on
the 24-bit functions, I noticed the following:

#ifdef Single
#define FLOAT float
#define FABS(x) (float)fabs((double)(x))
#define FLOOR(x) (float)floor((double)(x))
#define LOG(x) (float)log((double)(x))
#define POW(x,y) (float)pow((double)(x),(double)(y))
#define SQRT(x) (float)sqrt((double)(x))

This block shows that functions of type double are used when
running in Single mode.  To properly check the arithmetic,
this code should be changed to reference functions of type
float:

#ifdef Single
#define FLOAT float
#define FABS(x)  fabsf((x))
#define FLOOR(x) floorf((x))
#define LOG(x)   logf((x))
#define POW(x,y) powf((x),(y))
#define SQRT(x)  sqrtf((x))
