要在Go语言中将float 64值转换为字符串，而不使用指数（e）格式，可以使用strconv. numerFloat（）函数。

If the last token before a newline is an identifier (which includes words like int and float64), a basic literal such as a number or string constant, or one of the tokens break continue fallthrough return ++ -- ) } the lexer always inserts a semicolon after the token. This could be...

A RawStringLit is a string literal delimited by back quotes ``; the first back quote encountered after the opening back quote terminates the string. RawStringLit = '`' { utf8_char } '`' . `abc` `\n` Character and string literals are very similar to C except: - Octal character esca...

Seehttp://speleotrove.com/decimal/decifaq1.html#needed In particular there is one example where decimal128 doesn't provide enough precision Why arbitrary precision? See p3. Other use-cases: big.Float to string conversion, representing arbitrary precision numbers that are supported in other systems...
- structs must be identical (same decl) to be the same (Ken has different implementation: equivalent declaration is the same; what about methods?) - new methods can be added to a struct outside the package where the struct is declared (need to think through all implications) ...
// Int64 returns the number as an int64.func (n Number) Int64() (int64, error) {return strconv.ParseInt(string(n), 10, 64)} 类似的浮点数处理也一样,先按照字符串读取,这样可以避免内存分配,然后按需解析:github.com/json-iterator/go@v1.1.12/iter_float.go ...
