return ("%%.%sf" % n) % floatt
which works fine, but a question remains: n is an integer. Why the
's'
in '%sf'?
Its arbitrary. You could use %d just as easily.
%s will put the numner into the string, so will %d.
%d is probably a bit more picky about what it inserts - so might
actually be a better choice in this case since
float2n(1.234567, 3.5)
Doesn't work as you might hope... but changing it to use %d might -
depending
on your definition of better! And what you might hope! :-)
OTOH %s handles this better:
float2n(1.234567, '3')
maybe...
