[TxMt] Re: rounding bug in Math bundle...

[Timothy Bates]

math.tmBundle is using bc which is a powerful arbitrary precision  
programmable math engine (man bc)

I guess php et al. are rounding their results. I think bc can use  
BC_SCALE_MAX to force that, or the bundle could be re-written

All this being said: I think the bundle could use some love.

I'd very much appreciate a bundle that could add numbers in currency  
formats (i.e., strip off units and stick them back onto the answer. So  
this would work:
   £2 + .34

I'd also like the bundle to replace anything after an existing =
so  "2 + 2= 4" would not cause an error. That would allow editing of  
the inputs without having to also delete earlier results each time.

best wishes,
tim
