RETURN VALUE
If x or zero, returns x.
If x is NaN, returns NaN.
returns the properly signed infinity (or, in some non-default rounding
direction modes, the properly signed maximum-magnitude finite number)
in lieu of a value whose magnitude is too large, and raises the over‐
flow and inexact exceptions.
raises the underflow and inexact exceptions whenever a result is tiny
(essentially subnormal or zero) and inexact.
