Oracle functions can implement many functions. The Oracle functions described below are used to process decimal places. If you are interested in Oracle function databases, take a look. Oracle functions for processing decimal digits (): 1. Take the rounded decimal placesSelect round (1.2345, 3) from dual;Result: 1.235 2. retain the two decimal places.Select trunc (1.2345, 2) from dual;Result: 1.23 Select trunc (1.2399, 2) from dual;Result: 1.23 3. Take

Output For each data set, print: Trip # N: distance mph Of course n shocould be replaced by the data set number, distance by the total distance in miles (accurate to 2 decimal places) and mph by the speed in miles per hour (accurate to 2 decimal

Comment: Rounding the number to retain two decimal placesAket 6799 0:46:18It is not necessary to rounding the number into and keep two decimal places. Use the following code.To directly use the roundto function, you must add math to uses.Roundto (1.245,-2); = 1.25 It should be noted that the old Delphi version of the round function uses four homes and six inputs. In every five, the first entry is an odd number, and the last entry is an even number, ex

1. Round () function The parameter of this function must be of the floating point type. Therefore, the format must be converted first. If it is null, the conversion will fail. When the column is empty, the value 0.00 is displayed. This is not easy to understand. 2. formatnumber () function The format of this function is 123,456,567.00. "," Is added to the data. Not nice. The above two functions are combined with expressions and bound to fields. For example: = Formatnumber (sum (cdbl (Fields

JS How to implement a number to keep two decimal places after the decimal point:It is a common form to retain two decimal places after the decimal point, as it is relatively simple, the following examples are given directly below.The code is as follows:var num=3.1415926; Console.log (num.tofixed (2));The toFixed () function can refer to the toFixed () method section of the JavaScript number object.The origi

In php, functions such as sprintf, ceil, floor, and round are used to perform rounding. Let's take a look at the specific instance. This article will use php to round the number and retain N decimal places, and use php to round the number. (1) php keeps three decimal places and rounding them The Code is as follows: Copy code $ Num = 0.0215489;Echo sprintf ("%. 3f", $ num); // 0.022

Java: Rounding the double value to five, retaining the two decimal places, double rounding to five1. Functions The double value in the program is accurate to the two digits after the decimal point. It can be rounded up or truncated. For example, if the input value is 12345.6789, the output value can be 12345.68 or 12345.67. You can use the RoundingMode. UP/RoundingMode. DOWN parameter to determine whether to rounding the value ).2. Implementation Code

Python uses the floor function to discard decimal places. This article describes how to discard decimal places through the floor function in python. Share it with you for your reference. The specific analysis is as follows: In python, the floor function of the math library can be used to discard the decimal places behind the floating point. Import mathprint (m

Simple IntroductionWhen writing a data platform, it is necessary to make the statistic of passing rate, so it is unavoidable to have decimal condition. At this point, there will be an infinite number of decimals, then how to make a choice?Actual operationYou can use the decimal module, which is decimal, which provides decimal floating-point arithmetic support.Common methods1. Can be passed to a decimal integer or string parameter, but not floating point data, because the floating-point data itse

In the project, you use the truncation method to take two digits after the decimal point, so the following methods are written: Copy Code code as follows: Truncates a decimal value by the specified number of decimal places public static decimal ToFixed (decimal d, int s) { Decimal sp = Convert.todecimal (Math.pow (s)); if (d Return Math.truncate (d) + math.ceiling ((d-math.truncate (d)) * sp)/SP; Else Return Math.truncate (d) + Ma
