Ian:
You can use one of the Informix built-in functions:
Given:
table o_table with a decimal column issqty:
select TRUNC(issqty), ((issqty - TRUNC(issqty)) * 100) from o_table
is close to what you want. There is a built-in MOD function, but I'm unable to get it to work.
This should get you started.
Regards,
Ed
