positive and negative signs of the bit, in the lowest bit will be with the actual data error, in simple terms, we give the value, in In most cases it takes more than 64bit of digits to be accurately represented (even in the case of an infinite number of bits), whereas a double type has a value of only 64bit, and the number of digits behind it will definitely bring an error, and the result of "mathematically accurate" cannot be obtained.8,A: When using the BigDecimal (double) constructor, accura

technique for creating fast, Dynamic Web pages.　　The ability to update parts of a Web page without reloading the entire page. Ajax enables Web pages to be updated asynchronously by exchanging small amounts of data in the background with the server. This means that you can update a part of a webpage without reloading the entire page. Traditional Web pages (without Ajax) if you need to update the content, you must reload the entire page page. 2.2 Effects:2.2.1 Ajax uses asynchronous data transfer

provides the capability extensibility of components and other server-side objects by customizing them. Faster compilation times It validates the expression language at compile-time. High performance rendering capabilities. JSF (JavaServer Faces) technology supports a variety of tag libraries to add components to a Web page. To support the JavaServer Faces tag library mechanism, Facelets uses XML namespace declarations.The following table shows the tag libraries supported by the
