cell2csv (io package): Higher precision of floating point numbers?

[Martin Kunz]

Hi,

Is there a way to increase the precision of the floating point numbers
that are written by cell2csv? It seems to be 6 significant digits at the
moment which is probably fine in most cases. However, I would like to
write geographic coordinates in decimal degrees and cannot achieve the
desired sub-metre resolution with "only" six digits.

Thanks for your help,

Martin
