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. Scientific calculation.float price=1.2;Decim

Decimal (P[,s]), where p is precision and S is the number of decimal digitsP (Precision) The total number of decimal digits that can be stored, including the number of digits to the left and right of the decimal points (Number of decimal places) the maximum number of digits

. Net decimal retains the specified decimal places (not rounded),. netdecimal Preface 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 negative number when the last part is apportioned. Therefore, I wrote a method to retain the decimal digits of the specified number. The

Convert decimal to binary:The result is 1 after 2 rounds.Write the remainder and the last 1 in descending order as the result.For example, 302302/2 = 151 + 0151/2 = 75 + 175/2 = 37 + 137/2 = 18 + 118/2 = 9 + 09/2 = 4 + 14/2 = 2 + 02/2 = 1 + 0The binary value is 100101110. Convert binary to decimalStart from the last digit and column it as 0th, 1, 2...The number (0 or 1) of the nth digit multiplied by the Npower of 2The result is the answer.Example: 0

Python determines whether the instance is a positive decimal or a positive integer, and python decimal Python determines whether an instance is a positive decimal or a positive integer. Implementation Code: Def check_float (string): # The input amount may be decimal or integer s = str (string) if s. count ('. ') = 1

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 decimal

This article mainly introduces the Java method to keep the double type two decimal places, please refer to the use of itCopy CodeThe code is as follows:Mport Java.text.DecimalFormat;DecimalFormat df = new DecimalFormat ("##### #0.00");Double D1 = 3.23456Double d2 = 0.0;Double d3 = 2.0;Df.format (D1);Df.format (D2);Df.format (D3);The 3 results were:Copy CodeThe code is as follows:3.230.002.00Java retains two-bit de
