double infinity(void);
float infinityf(void);
long double infinityl(void);
double quiet_nan(long n);
float quiet_nanf(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.
