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