Selects the width of the output product real and imaginary components.
The values are automatically initialized to provide the full-precision
product when the A and B operand widths are set. The natural width of a
complex multiplication is the sum of the input widths plus one. If Output
Width is set to be less than this natural width, the least significant bits
are truncated or rounded, as selected by the next GUI field.Note: When the Floating Point data type
is selected, this field is disabled and its value is fixed to 32
bits.
