![]() if you liked it, please share your thoughts in comments section and share it with others too. That’s all for how to convert string to int type in Go programming language. Int64, 0, strconv.ParseInt: parsing "10S10": invalid syntax References Sixth, error := strconv.ParseInt(numDec, 10, 64)įmt.Printf("%T, %v, %v\n", sixth, sixth, error) Third, _ := strconv.ParseInt(numBinary, 0, 32)įourth, _ := strconv.ParseInt(numHexaDec, 16, 32)įifth, _ := strconv.ParseInt(numBin, 2, 32) Second, _ := strconv.ParseInt(numHexaDecimal, 0, 64) Syntax func ParseInt(str string, base int, bitSize int) (i int64, err error) Example package mainįirst, _ := strconv.ParseInt(numDecimal, 0, 8) If the value corresponding to string cannot be represented by a signed integer of the given size, then range error ( err.Err = ErrRange) is returned and the returned value is the maximum magnitude integer that can be fit to the given bitSize. ![]() In line 14, we concatenate 2 in str then print it. In line 13, we declare a string str, which we want to convert into an integer. In line 10, program execution starts from the main() function in Golang. When string is empty or contains invalid digits, then syntax error ( err.Err = ErrSyntax) is returned and the returned value is 0. In line 6, we import the string conversion package strconv, which is used to convert the string to other datatypes. In line 16, we convert the string str to int using the Atoi() function, and we assign the two returned values to variables n and err. Any base value which is 1, or below 0, or above 36 results in an error. Example 2: Addition of string and integer Using Explicit Conversion. In line 10, program execution starts from the main() function in Golang. Golang convert json value from int to string. ![]() Is it a good practice to maintain an exact copy of the struct. If base value is 0, then base is implied by the string’s prefix, “ob” for base 2, “o” for base 8, “ox” for base 16 and if no prefix is given then base 10. Is there a way to convert string to integer during unmarshlling without adding json tag like (json:',string') against the integer field. The bitSize value can be of four type, 0 for int, 8 for int8, 16 for int16, 32 for int32 and 64 for int64 data type, any value below 0 and above 64 results in an error. The function ParseInt converts the string in the given base (0, 2 to 36) to a integer number with the precision specified by bitSize value passed as an argument. In this tutorial, we will learn about how to convert string to int type in Go programming language.
