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...
