• The largest value that the answer memory can hold is one with 15 digits for the

mantissa and 2 digits for the exponent.

• Answer memory contents are not cleared when you press the A key or when

you switch power off.

• Note that answer memory contents are not changed by an operation that

assigns values to value memory (such as: faaAw).

next calculation. To do so, use the result of the previous calculation, which is
