Bug description:  sprintf function doesn't print correct results

Sometimes (1-10 times a day) appears a fatal bug
in my php code. Sometime this sprintf expression returns me string like
'0.05-0%':

<?echo
$rs["pol_sazbadph"]."-".sprintf("%1.0f",$rs["pol_sazbadph"]
*
100)."%"?>

This bug appears to me on two different servers:

1) Athlon based 2.4.12-k6 kernel - Apache/1.3.22 - php 4.1.0 RC3

 './configure' '--prefix=/usr' '--with-apxs=/usr/bin/apxs'
'--with-config-file-path=/ etc/php4/apache'
'--with-ibm-db2=/home/db2inst1/sqllib' 

2) Pentium II based - 2.2.19pre17 kernel - Apache/1.3.9 - 
php 4.0.3pl1

'./configure' '--prefix=/usr' '--with-apxs=/usr/bin/apxs'
'--with-regex=system' '--with- config-file-path=/etc/php4/apache'
'--with-db2' '--with-zlib' '--without-pgsql' '--
disable-static'
'--with-layout=GNU' '--with-zlib-dir=/usr' '--with-mysql=shared,/usr'
'--
with-ibm-db2=/home/db2inst1/sqllib'

The bug appears after we have compiled php against db2 libraries. I've
found another bug in sprintf with the same frequency of appearance in bugs
database. There is something bad in sprintf in some cases, but what?
