68 in such a way that underflow will not happen, and overflow
69 occurs only if the final result deserves it.
75 functions compute the complex absolute value of
84 .Sh ERROR (due to Roundoff, etc.)
88 .Fn hypot "5.0" "12.0"
91 in general, hypot and cabs return an integer whenever an
92 integer might be expected.
102 might be surprised at first to discover that
103 .Fn hypot "\(+-\*(If" "\*(Na"
105 This is intentional; it happens because
106 .Fn hypot "\*(If" "v"
113 .Fn hypot "\*(If" "v"
116 Unlike the reserved operand fault on a
121 disappear when it turns out to be irrelevant, as it does in
122 .Fn hypot "\*(If" "\*(Na" .
