Re: variables `inheriting' values, rounding

[Mike B.]

Sorry for the HTML email-I've now selected `plain text' in yahoo mail so hope 
this helps.

I'll look into your suggestions regarding settings parameter as a function.

I'm familiar with round, but was wondering if there is a already a pre-defined 
`round' function which accepts the accuracy as a parameter. 

Cheers.
