Make bcmath functions more strict

Hello everyone!

Recently I noticed that there are strange behavior going on if I use
bcmath functions (some examples you can see here
https://3v4l.org/D3s7J). I also previously had little discussion with
Sara Golemon on twitter about this
(https://twitter.com/SaraMG/status/1087902930110480384). So to
conclude things that I want, is drop behavior (they should throw
invalid argument exception) that I've showed in the first link and as
Sara suggested add deprecation warning (but I think it should be
E_NOTICE level errors) in 7.4.

Another option to consider is to adopt the same approach as standard
math in PHP. Here’s an example using standard addition for the same
values: https://3v4l.org/iMGg8

So, maybe it should emit notices and warnings instead?

Notice: A non well formed numeric value encountered in…
Warning: A non-numeric value encountered in…

Cheers,
Ben

Ha! I like your idea Ben. Should I make RFC? Since no one else responded
