string formatting - How can I round and print a floating point number in a minimum width format in Perl -

i wanted like:

printf('%3.3f%% ', $percent); 

but i'm still getting output as:

99.999% 100.000% 

i like:

 99.999% 100.000% 

so pads less full width spaces. format specifier accomplish i'm trying do?

the number before dot represents minimum value full field width, need 7 in there allow 3 digits before , after decimal point, , 1 more point itself:

printf "%7.3f%%\n", $_ 99.999, 100; 

output

 99.999% 100.000%
