I agree with you, how about having the bcmath extension support a more
general (and even better, non-BC-breaking) function supporting the
order of math operations (and maybe even math functions)... Something
like a bc(string $operations [, int $scale =3D 2])

Supporting passing: bc("(29.99 + $a) * $b - pow(10, $c) / 2");

Came across something like that in the manual: http://php.net/ref.bc#107014
How's that for a quick 'n dirty idea to solve this issue?
