The finitel() function shall test whether
its argument is neither INFINITY
nor
not a number (NaN).
On success, finitel() shall return 1. Otherwise the function shall return 0.
Note: The ISO C (1999) standard defines the function isfinite(), which is more general purpose. The finitel() function is deprecated, and applications should use isfinite() instead. A future revision of this standard may remove this function.
