BigFloat.pm module

how do i use the ffround() function in BigFloat.pm?
i'd try something,but the output is not what i want.here's my code.

#!usr\bin\perl

use Math::BigFloat;

print "Enter input:";
$string = <STDIN>;
chomp $string;

$f = Math::BigFloat->new($string);

$value = $f->ffround(zero);

print $value;

for example..i keyed in 22.3..and the output displayed is
+22E+0.can i have some advice..please?

printf "%.3f\n", $f->ffround(0);
