Can you clarify what you mean by "math libraries"? I may be naive here in the assumption that for most numeric datatypes there is an hardware support.....(?) The only datatype that "requires" special consideration AFAIK is DECIMAL and BCD math is not that hard that it requires a "library"... I wouldn'y exactly use an SQL Function to compute PI to 100 digits... Cheers Serge -- Serge Rielau DB2 SQL Compiler Development IBM Toronto Lab
