However, the touch screen calculator of the prior art can only realize the calculation function corresponding to the calculation function information stored in the calculation function module. When the touch screen calculator needs to perform personalized calculation functions, such as the calculation of personal income tax or exchange rate conversion, due to the There is no calculation function information corresponding to the above calculation function in the function module. The above calculation function needs to be calculated according to the personal income tax or exchange rate conversion formula. The data of the operation and the operation function command of the corresponding operation are issued several times to obtain the operation result data, which is cumbersome to operate the touch screen calculator

Embodiment 1
[0062] Example 1, assuming that the calculation method of personal income tax is: the amount of the monthly salary exceeding 2,000 yuan is calculated as the taxable part, and when the taxable part is within the range of 0 to 500 yuan, 5% of the taxable part is collected Personal income tax; when the taxable part is within the range of 500 to 1,000 yuan, 10% of the additional taxable part exceeding 500 is personal income tax. If the monthly salary is 3,000 yuan, the formula for calculating personal income tax is: (3000-2000-500)*10%+500*5, and the calculation result data of personal income tax obtained by using the existing technology touch screen calculator 300 needs to be input into the above formula in turn Multiple data and various operation function instructions can get the operation result data.
[0063] In the present embodiment, at first, write the multi-step operation information of individual income tax in the multi-step operation function module 42 by the touch-scree...

The invention provides a touch-screen calculator. The touch-screen calculator adopts a method for performing multi-step operation on input data which comprises the following steps of: firstly, configuring a multi-step operation functional module in the touch-screen calculator and writing multi-step operation information in the multi-step operation functional module; secondly, writing the correspondence between coordinates of input points on a touch screen and a multi-step operation functional instruction into a bottom application module so that a user sends the multi-step operation functional instruction by touching the touch screen; and thirdly, acquiring the multi-step operation information by a central processing unit and performing the operation on the input data by multiple steps according to the multi-step operation information to obtain an operation result. The operation steps of the multi-step operation are simplified for the user and the operation experience of the user is improved.
Description
technical field [0001] The invention relates to a personal terminal with a touch screen, in particular to a calculator with a touch screen and a method for performing multi-step calculations on input data. Background technique [0002] At present, personal terminals such as mobile phones and personal digital assistants (PDAs) generally use touch screens as user operation interfaces. When a touch screen personal terminal with a touch screen calculator This small and flexible tool brings great convenience to people's daily life. [0003] In the existing technology, such as figure 1 As shown, the structure of the touch screen calculator 100 includes: a central processing unit (CPU) 20 , an arithmetic function module 41 , a first memory 50 , a second memory 60 , a display module 30 , a touch screen 10 and an underlying application module 70 . [0004] The process for the user to send an instruction by touching the touch screen calculator 100 is as follows: the underlying appli...
