The original go language realizes the RMB small capitalization

This is a creation in Article, where the information may have evolved or changed.

Use the Golang regular expression to implement the RMB lowercase to uppercase, the code is as follows:

Package Mainimport ("RegExp" "StrConv" "Log" "FMT") func convertnumtocny (num float64) string {strnum: = StrConv. Formatfloat (num*100, ' F ', 0, ") sliceunit: = []string{" thousand "," Bai "," pick "," billion "," Qian "," Bai "," pick "," million "," Thousand "," Bai "," pick "," Yuan "," angle "," min " }//log. Println (Sliceunit[:len (Sliceunit)-2]) S: = Sliceunit[len (Sliceunit)-len (strnum): Len (sliceunit)]upperdigitunit: = map[string]string{"0": "0", "1": "One", "2": "II", "3": "Three", "4": "The Restaurant", "5": "WU", "6": "Lu", "7": "Qi", "8": "Ba", "9": "Jiu"}STR: = "" For K, V: = Range strnum[:] {str = str + upperdigitunit[string (v)] + s[k]}reg, err: = RegExp. Compile (' Certer $ ') str = Reg. Replaceallstring (str, "whole") Reg, err = RegExp. Compile (' 0 pt. ') str = Reg. Replaceallstring (str, "0") Reg, err = RegExp. Compile (' 0 min $ ') str = Reg. Replaceallstring (str, "whole") Reg, err = RegExp. Compile (' 0 [thousand picks] ') str = Reg. Replaceallstring (str, "0") Reg, err = RegExp. Compile (' 0 {2,} ') str = Reg. Replaceallstring (str, "0") Reg, err = RegExp. Compile (' 0 ') str = Reg. Replaceallstring (str, "billion") Reg, err = RegExp. Compile (' 0 ') str = Reg. Replaceallstring (str, "million") Reg, Err = Regexp.compile (' 0 * yuan ') str = Reg. Replaceallstring (str, "meta") Reg, Err = Regexp.compile (' billion zero {0, 3} million ') str = Reg. Replaceallstring (str, "^ Yuan") Reg, Err = Regexp.compile (' 0 yuan ') str = Reg. Replaceallstring (str, "0") if err! = Nil {log. Fatal (ERR)}return Str}func main () {FMT. Println ("12345.78 capitalized amount:", Convertnumtocny (12345.78))}

The result of the above code execution is as follows (you can use the CONVERTNUMTOCNY function to enter any conversion amount as an argument):

We often need a large amount of data to reduce the efficiency of our reading data, you can use Golang to add Chinese identity segmentation to increase the readability of the digital, the code is as follows:

package mainimport ("strings""strconv""fmt")func ConvertNumToCap(num float64) string{    strnum := strconv.FormatFloat(num, 'f', 2, 64)    capitalSlice := []string{"万","亿","兆"}    index := 0    result := ""    sdivision := strings.Split(strnum,".")    sl := sdivision[0]    if len(sdivision)>1{        result="."+sdivision[1]    }    // slength := len(sl)    for len(sl)>4{        result = capitalSlice[index]+sl[len(sl)-4:] + result        index = index+1        sl = sl[0:len(sl)-4]    }    result = sl+result    result = strings.Replace(result,"万0000","万",-1)    result = strings.Replace(result,"亿0000","亿",-1)    result = strings.Replace(result,"兆0000","兆",-1)    result = strings.Replace(result,"亿万","亿",-1)    result = strings.Replace(result,"兆亿","兆",-1)    return result}func main() {   fmt.Println("123450000.78的金额转换为：",ConvertNumToCap(123450000.78))}

The result of the above code execution is as follows (you can use the Convertnumtocap function to enter any conversion amount as an argument):
