No, it doesn't.

As posted, it outputs:

$str: .123456

when executed on Win7 with 5.014:

Update: Head slap moment!

Are you getting a different output? If so, with which perl version?

No it doesn't. Truncating the original value is left as an exercise (already solved) by OP. So...

#!/usr/bin/perl
use 5.014;

# 964932

my $str;
my $val = 0.123456;

my $fmt = '%.3f';
 my $val_trunc = sprintf $fmt, $val;

($str = $val_trunc ) =~ s/^0//;
say "\$str: $str";

[download]

Output: $str: .123
