Test program:

$n=16.9;
print intval($n*100)."<br>";  // why does this return 1689
print ($n*100)."<br>";

returns:

1689
1690


my configure line (from PhpInfo() )

'./configure' '--enable-track-vars' '--with-gd=/usr/local' '--with-zlib-dir=/usr' '--with- png-dir=/usr' '--with-sybase=/opt/sybase-11.9.2' '--with-apxs=/usr/local/apache/ bin/apxs' '--without-mysql' '--with-pdflib' '--enable-shared=no'
