In. when operating databases in. net, we recommend that you use parameterization to pass values. However, this may cause some doubts, for example, how can we maintain the same precision and decimal places as in the database when using decimal? You can use the precision and scale attributes of the parameter, for example: /// /// Update a piece of data/// Public dictionaryentry update_dictionaryentry (sde

The default decimal declaration in Java is double; such as: float x = 1.0, error, need to write: float x = 1.0f; * Float means that the single-precision floating-point number occupies 4 bytes in the machine and is described with a 32-bit binary* Double indicates that the double-precision floating-point number occupies 8 bytes in the machine, and is described in 64-bit binary binary* For programmers, the difference between double and float is that the

Adjust the decimal format, such as retaining the last two digits of the decimal point, the following articles collect some good implementation methods and share some of them. During the development process, we often encounter the need to adjust the decimal format, such as retaining the last two digits of the decimal po

I have such a set of data Pseudo-code (now saved with a string, then converted) "buy": [{ "p": "1698.64000", "n": "0.117" }, { "p": "1698.63000", "n": "5.000" }, { "p": "1696.54000", "n": "0.128" }, { "p": "1696.34000", "n": "0.176" They have fixed decimal places, p is fixed and there are up to 2 significant digits after the decimal point, and N is a maximum of 3 digits after t

exponential digits; 51-0 bits, a total of 52 bits are the ending bits. According to the IEEE floating point number representation, the double Floating Point Number 38414.4 is converted to the hexadecimal code below. Enable integer and decimal parts: Convert integer parts directly into hexadecimal: 960E. Decimal processing: 0.4 = 0.5*0 + 0.25*1 + 0.125*1 + 0.0625*0 + ...... In fact, this will never end! T

Today, in C #, you encounter a problem that requires you to convert a double to a string display, requiring you to keep the decimal digits.Check out the relevant articles on the InternetSpecific as follows:Double temp=3.1415926;F Fixed point:string str1=temp.tostring ("F1");//Keep one decimal rounding Result: 3.1F Fixed point:string str2=temp.tostring ("F2");//reserved Two

The project uses the truncation method to get the last two digits of the decimal point, so the following method is written: Copy codeThe Code is as follows: // /// Truncates a small value by a specified decimal point /// /// /// /// Public static decimal ToFixed (decimal d, int s) {

The problem that the decimal type of linq is saved to the database is saved to only two digits after the decimal point, linqdecimal The problem of saving a decimal type to data today has plagued me for a long time, finally, a small setup problem is solved ···· If you don't talk much about it, just ask the question and say the answer: Problem: when using EF DbCont
