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。

round: round float to n decimal places mutate: creates new columns from selected fields by regular expression mutate2: creates a new column from selected fields by awk-like arithmetic/string expressions mutate3: create a new column from selected fields with Go-like expressions ...
comparison: Cmp, TotalCmp (http://speleotrove.com/decimal/decifaq4.html#order) format conversion: to/from int64, uint64, float32, float64, big.Float, big.Int, big.Rat to/from string conversion Implementation of the above operations closely follows theGeneral Decimal Arithmetic Specification. Th...
Instead the lexer uses a simple rule to insert semicolons automatically as it scans, so the input text is mostly free of them. The rule is this. 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 ...

The above code imports therectanglepackage and uses theAreaandDiagonalfunction of it to find the area and diagonal of the rectangle. The%.2fformat specifier in Printf is to truncate the floating point to two decimal places. The output of the application is ...
