Ran into issues with exacting the NC_FLOAT variables output by ncks with
Java floats. Thought I would share my experience. If anyone has a
better way of doing this, please do share.
The issue stems from the fact that Java stores float variables in binary
and some values (like 0.2) can't be represented in binary. ncks always
returns floats with 6 decimal places.
ncks -s '%f' -v VARIABLE NETCDF_FILE
I got an equivalent output in Java doing the following:
import java.math.BigDecimal;
...
float var = ... // (Code to get variable into a Java float excluded)
BigDecimal big_var = new BigDecimal(var);
String ncks_formated_var = big_var.setScale(6,6).toString();
