LEXIBOOK GC1000i, Instruction Manual, Page: 22 / 75

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
immediately before can be
omitted.
Example : 15 x 3 = 45 78 x 45 – 23 = 3487
15 3
78 23
2.2.2 Continuous calculation function
Even if calculations are concluded with the key, the result obtained can be used for further calcula-
tions. Such calculations are performed with 10 digits mantissa of the displayed value.
Example 1: To calculate ÷ 3.14 after 3 x 4 = 12 Example 2: To calculate 1 ÷ 3 x 3
3 4 1 3 3
(Continuing) 3.14 1 3
(Continuing) 3

2.2 SPECIAL FUNCTIONS
2.2.1 Answer function
The answer function stores the result of the most recent calculation. Once a numeric value or numeric
expression is entered and
is pressed, the result is stored by this function.
To recall the stored value, press the key. When is pressed, “Ans” appears on the display along
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 = 579 789-579 = 210
123 456
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
is pressed, the
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 key, that value is not stored in the
Ans memory.
Example: Perform calculation 78+56=134, then store the value 123 to memory A:
