Editor to share with you how to achieve the conversion of string, int and float in go. I hope you will get something after reading this article. Let's discuss it together.

String to other string-- > int: convert the string 13 to a numeric value of type int 13str: = "13" distInt,err: = strconv.Atoi (str) string-- > int64: convert the string 13 to int64 (decimal) / / Parameter 1: with converted string, / / Parameter 2: based on the decimal system, the value can be 0per8, 16, 32, 64, 3: which int type to convert: 0, 8, 16, 32, 64 Corresponding to int,int8,int16,int32,int64distInt64, err: = strconv.ParseInt (str, 10,64) string-> float64, float32// ParseFloat converts a string to a floating point number / / str: string to convert / / bitSize: specify floating point type (32:float32, 64:float64) / / if str is a legal format and is close to a floating point value / / returns the floating point rounding value (according to IEEE754's rounding criteria) / / returns "syntax error" if str is not a legal format / / if the conversion result is outside the bitSize range Return "out of range" / / to float64distFloat,err: = strconv.ParseFloat (str,64) / / to float32distFloat,err: = strconv.ParseFloat (str,32) int, int64 to another int-> stringi: = 11str1: = strconv.Itoa (I) / / or str2: = strconv.FormatInt (int64 (I), 10) int64-> stringdistStr: = strconv.FormatInt (num) 10) float to other float-- > string// FormatFloat converts floating point number f to string value / / f: floating point number to convert / / fmt: format tag (b, e, E, f, g, G) / / prec: precision (length of numeric part) Does not include index part) / / bitSize: specify floating point type (32:float32, 64:float64) / / format tag: / /'b' (- ddddp ±DDD, binary index) / /'e' (- d.dddde ±dd, decimal index) / / E' (- d.ddddE ±dd, decimal index) / /'f'(- ddd.dddd, no index) / /'g' ('evalues: large index) / / prec represents the number of digits after the decimal point / / if the format is marked as' estrangement,'or 'fags, then the number of digits after the decimal point / / if the format is marked as' gallop Then prec denotes the total number of digits (integer part + decimal part) str1 = strconv.FormatFloat (11.34 string strconv.ParseFloat (str1,32) fmt.Println (h) / 11.340015258789h). _ = strconv.ParseFloat (str2,64) fmt.Println (h) / / 10.55float64-- > int64 (there will be a loss of accuracy) var x float64 = 6.9y: = int64 (x) finished reading this article I believe you have a certain understanding of "how to convert string, int and float in go".
