When you execute the sql command to run the copy.out and copy.in scripts, the floating point specification defaults to 10 positions with 3 to the right of the decimal. If your data requires more precision, change the precision mask by using the ‑f flag with the sql command when you run the copy.out and copy.in scripts.

For a description of the floating point (-f) flag parameters that is used with the sql command, see the Command Reference Guide.
