The arithmetic data types are listed below in the order of their efficiency (most efficient first). Most working variables should use the FIXED BIN(31) data type.
To ensure that you do not get the wrong implicit attributes and/or precision, for non-PIC items always specify at least FIXED or FLOAT and BIN or DEC with appropriate precision. Micro Focus recommends that you use the -nolaxdcl compiler option to warn if you are not following these guidelines, in addition to getting warnings for contextual declarations.
The following data types are highly discouraged as arithmetic data types:
