From 4ab8b2dd6e571b8dafe69a4d7a09a451cc9b1645 Mon Sep 17 00:00:00 2001 From: Manuel Novoa III Date: Tue, 19 Jun 2001 22:53:41 +0000 Subject: Remove Erik's broken implementation of rint(). Replace it by one "less broken". Also correct rounding beharior of round() and add trunc(). Note that round() and rint() currently don't check for infs and nans. I decided to wait on that until the big cleanup. --- libm/double/rint.c | 52 ---------------------------------------------------- 1 file changed, 52 deletions(-) delete mode 100644 libm/double/rint.c (limited to 'libm/double/rint.c') diff --git a/libm/double/rint.c b/libm/double/rint.c deleted file mode 100644 index 35cf5f503..000000000 --- a/libm/double/rint.c +++ /dev/null @@ -1,52 +0,0 @@ -/* vi: set sw=4 ts=4: */ -/* - * rint for uClibc - * - * Copyright (C) 2001 by Lineo, inc. - * Written by Erik Andersen , - * - * This program is free software; you can redistribute it and/or modify it - * under the terms of the GNU Library General Public License as published by - * the Free Software Foundation; either version 2 of the License, or (at your - * option) any later version. - * - * This program is distributed in the hope that it will be useful, but WITHOUT - * ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or - * FITNESS FOR A PARTICULAR PURPOSE.
