SYNOPSIS
       cc [ flag ... ] file ...	 -lsunmath -lm [ library ... ]

       #include <sunmath.h>

       double min_subnormal(void);

       float min_subnormalf(void);

       long double min_subnormall(void);

       double max_subnormal(void);

       float max_subnormalf(void);

       long double max_subnormall(void);

       double min_normal(void);

       float min_normalf(void);

       long double min_normall(void);

       double max_normal(void);

       float max_normalf(void);

       long double max_normall(void);

       double infinity(void);

       float infinityf(void);

       long double infinityl(void);

       double quiet_nan(long n);

       float quiet_nanf(long n);

       long double quiet_nanl(long n);

       double signaling_nan(long n);

       float signaling_nanf(long n);

       long double signaling_nanl(long n);

DESCRIPTION
       These  functions	 return	 special  values associated with ANSI/IEEE Std
       754-1985 floating-point arithmetic.

       min_subnormal()	returns	 the  smallest	positive   subnormal   number.
       max_subnormal() returns the largest positive subnormal number.

       min_normal() returns the smallest positive normal number (the underflow
       threshold).  max_normal() returns the largest positive subnormal number
       (the overflow threshold).

       infinity() returns positive infinity.

       quiet_nan(n) returns a quiet NaN.  signaling_nan(n) returns a signaling
       NaN.  The parameter n is not used.
