From f674c13c781e76c4b77c1c1fe5e0e3c6ac48b07c Mon Sep 17 00:00:00 2001 From: David Schultz Date: Mon, 21 Feb 2005 16:04:23 +0000 Subject: [PATCH] Remove the i387 versions of atan(), atan2(), and atan2f(). They are slower than the MI routines on modern hardware, except for degenerate cases such as the Pentium 4.
