Problems solved by technology

[0003] Or there is a calculator sold on the market, which can record all the operation process of the user, but it cannot make the user record only the required items and calculate the total, and it also needs to record all the calculation processes. It consumes considerable memory capacity and increases the price of IC
If the user only wants to know each subtotal and calculate the surplus, and does not need to check the calculation process, the above calculator is not suitable

Embodiment Construction

[0026] see figure 1 , is the architecture diagram of the calculator of the present invention. Its components include a liquid crystal screen 1, a microprocessor 2, a memory 3 and input buttons 4, etc., wherein the liquid crystal display 1 is used for users to consult; the microprocessor 2 is used for processing and computing data, and the memory 3 is used for To store the software program used by the calculator, the input calculation temporary storage data and the project data required by the operator to arbitrarily select and record; the input button 4 is for the user to input data, and the input button 4 is provided with a button for the operator to perform a summary function Button group, the button group has summary (summary), mode (mode), query (↑, ↓), clear (C), insert (+), data summary operation (=) and print (#) keys 41-48, etc. ,like figure 2 .

[0027] In this way, the user can arbitrarily select the required item data, and store the item data in the memory 3 for...

Abstract

A method for making a calculator have summary function features an additional program is used to run, which can make the calculator come in summary mode. In the summary mode, all the data stored in the memory can be summerized.

Description

technical field [0001] The invention relates to a method for a calculator with summarizing functions, in particular to a method for enabling the calculator to have the functions of account comparison and surplus calculation. Background technique [0002] The functions of current calculators can only record the sum of a certain subtotal, direct addition or subtraction (such as: M+, M-..., etc.), but if a general store wants to choose to record the data of a certain subtotal, so that Comparing each result one by one, or summarizing, as one or one week's bookkeeping or surplus statistics, there is no suitable function at present. [0003] Or there is a calculator sold on the market, which can record all the operation process of the user, but it cannot make the user record only the required items and calculate the total, and it also needs to record all the calculation processes. It consumes considerable memory capacity and increases the price of the IC. If the user only wants ...
