A Ans Update and Delete Timing

When using Ans in a calculation, it is important to keep in mind how and when its contents change. Note the following points.

•The contents of Ans are replaced whenever you perform any of the following operations: calculate a calculation result, add a value to or subtract a value from independent memory, assign a value to a variable or recall the value of a variable, or input statistical data in the SD Mode or REG Mode.

•In the case of a calculation that produces more than one result (like coordinate calculations), the value that appears first on the display is stored in Ans.

•The contents of Ans do not change if the current calculation produces an error.

•When you perform a complex number calculation in the CMPLX Mode, both the real part and the imaginary part of the result are stored in Ans. Note, however, that the imaginary part of the value is cleared if you change to another calculation mode.

A Automatic Insertion of Ans in Consecutive Calculations

If you start a new calculation while the result of a previous calculation is still on the display, the calculator will insert Ans into the applicable location of the new calculation automatically.

Example 1: To divide the result of 3 × 4 by 30

3*4w

3

× 4

 

 

 

12

 

 

 

 

An s ÷30

(Next) /30w

 

04

 

 

 

Pressing / inputs Ans automatically.

Example 2: To determine the square root of the result of 32 + 42
3x+4xw3 2 +4 2

25

 

 

 

9w

'( Ans

5

 

Note

•As in the above examples, the calculator automatically inserts Ans as the argument of any calculation operator or scientific function you input while a calculation result is on the display.

•In the case of a function with parenthetical argument (page 10), Ans automatically becomes the argument only in the case that you input the function alone and then press w.

•Basically, Ans is inserted automatically only when the result of the previous calculation is still on the display, immediately after you executed the calculation that produced it. See the next section for information about inserting Ans into a calculation manually with the K key.
