Abstract

A method for implementing the formula editing, calculating and managing on PDA includes invoking the formula managing module to display the main interface which is composed of such function keys as increase, delete, edit, naming, calculation, preserve and exit, and clicking one of said function keys to implement relative function, such as edit and calculation for invoking the formula editing module and calculating module.

Description

technical field [0001] The invention relates to a method for realizing editing, calculating and managing mathematical formulas, in particular to a method for realizing editing, calculating and managing mathematical formulas on a handheld computer (pda, portable computer). Background technique [0002] At present, many tasks require mathematical calculations. For example, accounting, statistics, engineering and other industries involve the use of existing data for analysis and calculation. If the analysis process is very complicated, such as using some professional calculation models to iteratively calculate, it is generally necessary to input the data into the computer and use computer software to perform calculation and analysis. If you encounter relatively simple data processing problems, use some calculation methods Formulas can be used to calculate the required results, and mathematical calculators are generally used for calculations. [0003] Using calculators to deal ...
