| Note: | Beginning in 2025.12 this function supports the BIGINT data type when run in the DS2 language. Set BIGINTPROCESSING=YES to ensure BIGINIT functionality. If any argument is DOUBLE, all arguments are converted to DOUBLE and the result is DOUBLE. If BIGINTPROCESSING=YES is set in the PROC DS2 statement and any argument is BIGINT, all arguments are converted to BIGINT and the result is BIGINT. |
