Avoid divide by zero

Added by Marston Ward about 12 years ago

Hi,

How do you, if you can, divide two variables in a file and avoid dividing by zero? I thought about doing this using expr,'var=(1 - x/y)' but y has 0 values.
I want to avoid modifying y and replacing the 0s. I looked at ifthen ifthenelse but these seem to work on separate files.
Any suggestions?

Hi Marton,

try to set 0 as a missing value using setmissval or setctomiss operators

Cheers,
J.
