It's a pain in the ass to read because you have to LISP nest all the operations. You can't tell me this is easy or intuitive to read... bcadd( bcsub( $bill['penalty'], $bill['rounding'], 2),bcmul( $bill['taxdue'], bcmul( $penalty, $monthsAhead, 2 ), 2 ), 2 ) Compared to $bill['penalty'] - $bill['rounding'] + $bill['taxdue'] * $penalty * $monthsAhead; You can do it, but it's eye bleeding.
