[Brief Description :]This chapter focuses on the Value Type and reference type. The Value Type describes BigInteger and Nullable Section 1 Use of the numeric type 1. Automatic and forced conversion of value typesWhen the value type is changed from "large to small"-for example, if the double type is converted to the float type, forced conversion is required, which may cause data loss. Therefore, the code is considered as a defect code, you only need t

comparison, we should find a method that replaces the equivalent judgment on floating point numbers. An Effective Method: first determine the acceptable precision range, and then use Boolean Number to determine whether the value is close enough.3. Handling Rounding Errors4. Check the support of the language and function library for specific data types. 12.4 characters and strings1. Avoid using mysterious characters and strings (magic character an
