Numeric parameters, normally documented as "num" or "numeric," may be of any type supporting numeric values; this includes F (floating point), B (binary), I (signed integer), and even S (String). If the parameter contains or may contain a negative value, you should use either F or I. The size of the variable typically just needs to be large enough to handle the required values. If the parameter absolutely must be floating point or a particular size, it will be documented as such.
