The lead-in at Extension:BCmath is broken, and the “alternatives” section got a bit weird. It is not two alternatives, it is one alternative that has a C-part and a Lua part. Now it looks like there are two different alternative solutions.

This issue seems to be resolved. Keep sentences short and simple to make translation easier.
No it isn't, I just tried to clarify the present layout. It is still confusing.
About the lead in, it now reads “Special:MyLanguage/Help:Lua provides arbitrary-precision arithmetic to Lua modules.” The initial part is not correctly formatted.
Sorry!
Nah, I'm not very good at explaining things. Sort of expect people to read my mind.
