in reply to Golf: overtone calculator


just quickly,

Here's a slightly shorter version that still compiles under strict and warnings. i only have tested it under the single test case above, if it fails others please provide them and i'll try to correct it. Anyway, this weighs in at 66 characters:

sub Harmonics ($$) {
#23456789_123456789_123456789_123456789_123456789_123456789_123456789_
for$a(1..pop){$_{sprintf'%.3f',$_[0]*$a/$_}++for 1..$a}sort keys%_
}

    Impressing inner loop, but your sort will fail with $_[1] > 10, because it sorts lexically.

      Does this fix the problem? (at 72 chars):
      sub Harmonics ($$) {
#23456789_123456789_123456789_123456789_123456789_123456789_123456789_
+12
for$a(1..pop){$_{sprintf'%.3f',$_[0]*$a/$_}++for 1..$a}sort{$a-$b}keys
+%_
}

        I'm outta votes right now, but kudos for the $a-$b bit. D'oh..
