[Liblas-devel] floating point round off problem in libLAS Python API

I am trying to use libLAS Python API to write point data sets to *.las
file. But I am experiencing some problems with the floats values being
rounded off

>>> from liblas import point
>>> pt=point.Point()
>>> pt.x=2.323
>>> pt.x
2.0
>>>

If I set the pt.raw_x instead of pt.x I don't see the rounding off problem
but no las file is written.

>>> pt.raw_x=2.323
>>> pt.raw_x
2.323

I am not sure what am I missing. I would appreciate any help with this.

Thanks,
Jitu
