with the answer function value. The value can be used in subsequent calculations.
*** Since the "Ans" function works just like any other memory, it will be referred to as "Ans memory"
throughout this manual.
Example : 123+456 = 579
123
AC
789 -
Numeric values with 12 digits for a mantissa and 2 digits for an exponent can be stored in the Ans
memory. The Ans memory is not cleared even if the power is turned off. Each time
value in the Ans memory is replaced with the value produced by the new calculation. When execution of
a calculation results in an error, however, the Ans memory retains its current value.
When a value is stored to another memory using the
Ans memory.
Example: Perform calculation 78+56=134, then store the value 123 to memory A:

The Ans memory can be used in the same manner as the other memories, thus making it possible to
use it in calculation formulas. In multiplication operations, the
