If you just want 0.86, use number_format() or round() not a bug, Bogus ------------------------------------------------------------------------ [2002-04-09 08:03:23] sutter@ecology.at echo (18/21); returns 0.857142857142861. right is 0.86; my configure command: './configure' '--prefix=/usr' '--with-config-file-path=/etc' '--disable-debug' '--enable-pic' '--enable-inline-optimization' '--with-apxs=/usr/sbin/apxs' '--disable-static' '--enable-shared' '--with-exec-dir=/usr/bin' '--with-regex=system' '--with-gettext' '--with-gd' '--with-openssl'' -with-jpeg-dir=/usr' '--with-png' '--with-zlib' '--with-gdbm' '--with-kerberos' '--with-imap-ssl' '--enable-debugger' '--enable-magic-quotes' '--enable-safe-mode' '--enable-sysvsem' '--enable-sysvshm' '--enable-track-vars' '--enable-gd-imgstrttf' '--enable-yp' '--enable-ftp' '--without-mysql' '--with-xml' '--with-ttf' '--with-gnu-ld' '--with-mysql=shared,/usr' '--with-pgsql=shared,/usr' '--with-imap=shared,/usr' '--with-ldap=shared' ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=16511&edit=1
