Re: printf: zero pad after the decimal a given amount

Why is there no way to tell printf to zero pad like the right column:

One reason is that what you want is ill-defined. If we are going to tweak
sprintf to make it suit our personal preferences, I'd rather see a
conversion character that behaved just like %f if given a good number, but
returned the empty string if given either an empty string or undef (rather
than converting it to zero and then applying %f to the zero.)

0.1 :0.100
0.05 :0.050
0.03 :0.030
0.025 :0.025
0.02 :0.020
0.015 :0.015

Apparently you want to preserve non-zero digits even if that means going
beyond 3 digits right of the decimal. But why did you stop at 4?

0.014999999999999999444888

0.0125 :0.0125


0.0125000000000000006938893

How many consecutive zeros or nines are needed before you decide there are
enough to ignore what is the right of them?
