is there a trick to convert RealLiteral  numbers to strings without

For now, you can use the skip_zeroes argument to str:

sage: a=2.000000000000
sage: a
2.00000000000000
sage: a.str(skip_zeroes=True)
'2.'

I've written lots of code to make this feature more usable, but it's undergoing a design discussion/reimplementation now.

Thanks,

Jason
