The following is a user-defined addition function. Using this method for addition will avoid the above problem. // UDF addNum (num1, num2) {var sq1, sq2, m; try {sq1 = num1.toString (). split (".

Method 1: Use Math.Round to calculate the number format that is returned here.float price=89.89;int itemNum=3;float totalPrice=price*itemNum;float num=(float)(Math.round(totalPrice*100)/100);//如果要求精确4位就*10000然后/10000Method 2: Return with DecimalFormat in string format. The class is fully encapsulated in decimal. Like the% number, thousand bits, decimal precision.

In js, the most common method for getting the decimal point and the two decimal points is the rounding function. I have previously introduced this common function in js, which is useful here, next let's take a look at some methods to sum up the two digits after the float decimal point. Use Javascript to get the first two digits of the float

I have been engaged in ASP. NET in C # development for almost a year. Today I know that the truncation method is not used when the number of decimal places is retained in C.The project uses the truncation method to get the last two digits of the decimal point, so the following method is written:1 /// 2 // truncate a small value by the specified number of

C # decimal retains the specified decimal places, When decimal retains the specified decimal digits, the. NET method is rounding. If the project encounters a apportioned amount, the amount in the last line = total amount-sum of the apportioned amount. This may result in a ne
