Reference.

p

Restricted expression specifying the number of digits to be maintained throughout the operation.

q

Restricted expression specifying the scaling factor of the result. For a fixed-point result, if p is given and q is omitted, a scaling factor of zero is assumed. For a floating-point result, q must be omitted.

If both p and q are omitted, the precision of the result is determined from the rules for base conversion.
