[PD] symbol2list float error

Hi everyone,
I'm trying to read data from a GPS receiver connected to a serial port in a MacBook (Mac OS 10.6.3) running Pd-extended (v. 0.41.4). The GPS receiver sends floats with three decimal places, but I'm losing the last decimal place in the conversion process. I found that the truncation is being done at a [symbol2list] object inside a [convert.ascii2pd LF] abstraction (v 3.1), so if I print before and after this is what I get:
before: symbol 3731.428
after: 3731.43
before: symbol 13956.320
after: 13956.3
it seems to me that [symbol2list] is doing some rounding, how can I avoid it? the rest of the patch works like a charm but that last decimal place is crucial for this project. Could you guys help me?

On the other hand, why not simply

Hope some of this helps.
