Why is there no way to tell printf to zero pad like the right column:
Why do you assume that because you don't know the way, there is no
way?
0.1 :0.100
0.05 :0.050
0.03 :0.030
0.025 :0.025
0.02 :0.020
0.015 :0.015
0.0125 :0.0125
0.01 :0.010

The challenge: Change only the "WHAT?" below to produce the right
column above. Thanks.
use constant S => 100000;
for ( 10000, 5000, 3000, 2500, 2000, 1500, 1250, 1000, 900, 625, 500
) { printf "%-7g:WHAT?\n", $_ / S, $_ / S;
%.03f
$ perl -e'printf("%.03f\n", .1)'
0.100

Actually that truncates to 3 decimal places, which isn't what the op
required:
$ perl -e'printf("%.03f\n", .00625)'
0.006
See my other post for a working solution.
