Subject: [Caml-list] NaN-safe min and max
Date: Wed, 15 Oct 2003 10:52:06 -0400 (EDT) [thread overview]
Message-ID: <18220.141.155.88.179.1066229526.squirrel@minsky-primus.homeip.net> (raw)
Olivier Andrieu proposed the following code for doing a safe min/max.
Does anyone have any thoughts about this code snippet, and whether it is
or is not a safe use of Obj.magic?
let min a b =
let o = Obj.repr a in
if Obj.is_block o && Obj.tag o = Obj.double_tag
then Obj.magic (fmin (Obj.magic a) (Obj.magic b))
else Pervasives.min a b
