I have studied how to add, subtract, multiply, and divide JavaScript decimal places. I have also done some tests and gained a lot of knowledge, you can share an interesting test with us as follows: 0.1 + 0.2 = 0.3 // falseSuddenly depressed, okay! 0.1 + 0.2 changed to: 0.30000000000000004Another 2.4/0.8 => 2.9999999999999996 cannot be converted into an integer (2.4*100)/(0.8*100)10.22 now I want to subtract the result value of 0.11 and then there wil

PHP rounded to exact decimal places and rounded up. In php, functions such as sprintf, ceil, floor, and round are used to perform rounding. let's take a look at the specific instance. In this article, we will use php to perform four functions in php to take decimal places: sprintf, ceil, floor, round, and so on. let's take a look at the specific example. This article will use php to round the number and ret

ArticleDirectory Requirement Overview Implementation Requirement Overview In some statistical reports, the value range of a certain number is quite large. In order to reduce the total number of digits displayed for a large data, a small data must be displayed with sufficient precision, that is to say, different decimal places are displayed based on the data size, which is similar to the floating point mechanism that represents the

CSS filters to achieve the effect of frosted glassApple's IOS 7 brings us the "frosted glass" effect-a translucent, blurred element that looks like frosted windows. With the introduction of Apple, this effect can be seen in more and more places. It's a bit complicated to reproduce the effect--only fuzzy translucent images can be used to achieve the effect of the frosted glass before CSS

Problem description: When using EF's dbcontext to save the decimal type data to the database, the default is to save only the first 2 decimal places after the decimal point, the remaining 0 ; For example, save 101.182352152322, the actual data stored in the database is 101.180000000000;Workaround: When creating the project DbContext, override the Dbcontext.onmodelcreating () method, and then specify the precision by the following method:1 protected ov
