Re: note 9309 added to bcmul

I added the following editor's note to your comment: [Editor's note: It is not that the parameter is not optional, but that when using the bc* functions, you should defined the scale beforehand using bcscale(), e.g. in the example below you should use "bcscale(3);" before you use bcmul/bcdiv/etc.] --- chris.key@wcom.com wrote: > bcmul optional scale parameter is not optional. > Given the following code: > > echo "A: ".(2900000 / 500)."\n"; > echo "C: ".bcdiv( (290000 / 500), 290000, 5).
