LIBRARY
Math Library (libm, -lm)

-infinity < x < +infinity.
Otherwise a zero is returned (that is, |x| = infinity or x is NaN).
SEE ALSO

STANDARDS
The described functions conform to IEEE Std 754-1985. Note that unlike
isfinite(3), neither function is present in the ISO C-language standards
or in the IEEE POSIX standards.
HISTORY
The finite and finitef() functions first appeared in 4.3BSD.
