Many people think Android calculators are very powerful, because they not only implement the basic computing implemented by General computers. The Calculation of expressions such as "(6 + 3) * 3/5-34 + (3-5)" is implemented, which enables many primary school students to perform multiplier arithmetic operations, you can use this calculator to get the result at a time, greatly reducing the time overhead of the job. 1. core computing of Android

IntroducedWe have developed a tax calculator, after entering the salary, printing the tax payable.A tax calculation formula: Taxable income = Salary amount-Various social insurance costs-starting point (3500 yuan) Taxable amount = Taxable income x tax Rate-Calculator deduction Each of the social insurance costs we set in this procedure is 0, do not consider.The tax rate and the

Because it is a novice (very pure kind), so a bit messy, the code is very redundant (will be condensed later), naming rules please ignore. Of course, this calculator is only able to run up to the extent that there will be some inexplicable error, such as my index operation index only support integers and so on. After all, it is the first time to write a small thing alone, still very happy.1. Main section (Layout and click event ActionEvent monitoring)

Utility tools under Linux--calculators 1. BC Instruction addition, 4. BC Instruction Division (advanced), shown, 10/3 is 3, because we do not specify a decimal point after a few, the default is taken to the integer part, and 10/100 is zero, the same reason, only to take the integer 0 part. Use the "scale=[number" command to specify a few points after the decimal point:The BC Command calculates the remainder, 6. BC Command Count index, 87. How to exit the calculatorSince

The Set calculator can easily implement several common memory groups, such as equivalent groups, bitwise groups, and enumeration groups. The following describes the examples.Equivalent Group The equivalent grouping is based on the fields (or calculated columns derived from fields) of the current dataset. Each group is a subset of the original dataset. Example description: Group sales orders by order year. Data Description: The order data is as follows
