=item $#

The output format for printed numbers.  This variable is a half-hearted
attempt to emulate B<awk>'s OFMT variable.  There are times, however,
when B<awk> and Perl have differing notions of what counts as 
numeric.  The initial value is "%.I<n>g", where I<n> is the value
of the macro DBL_DIG from your system's F<float.h>.  This is different from
B<awk>'s default OFMT setting of "%.6g", so you need to set C<$#>
explicitly to get B<awk>'s value.  (Mnemonic: # is the number sign.)

Use of C<$#> is deprecated.
