ADD
ADD returns the sum of x and y with a precision specified by p and q. The base, scale, and mode of the result are determined by the rules for expression evaluation unless overruled by the PRECTYPE compiler option.
- x and y
- Expressions.
- p
- Restricted expression. It specifies 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 q is omitted, a scaling factor of zero is the default. For a floating-point result, q must be omitted.
ADD can be used for subtraction by prefixing a minus sign to the operand to be subtracted.
