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