[gradsusr] COPYGB

[Alvin Pura]

*Dear all,I run copygb with the following option as shown below:*



*grid='255 0 NX NY LAT0 LON0 128 LAT1 LON1 DX DY 0'
copygb -g"$grid" -x inxxx.grb outxxx.grb*




*However,upon checking (using wgrib -V option) I found out that the
min/max data on the New GRID shows a rounded off numbers instead of
having a four decimal value. Is someone has an idea how can I get the
same value as the Original GRID (with 4 decimal place value)?*

* Original GRID*
