By converting the string to an integer, you can easily work with the data and perform numerical operations on it. By converting the string to an integer, you can easily perform numerical operations on the data.Īnother use case is when working with external APIs that return data in the form of a string. So why would someone want to convert a string to an integer in Golang? One common use case is when working with user input data that is in the form of a string. We then print the “i” variable using the fmt.Println() function. We use the strconv.ParseInt() function to parse the “s” variable and convert it to an integer of 64 bits, which we store in a variable called “i”.
Convert string to integer golang code#
In the code above, we declare a string variable called “s” with a value of “123”. Here’s an example of the second method: package main We use the strconv.Atoi() function to parse the “s” variable and convert it to an integer, which we store in a variable called “i”. The second method is by using the strconv.ParseInt() function, which parses a string and returns an integer of a specific bit size. The first method is by using the strconv.Atoi() function, which parses a string and returns the corresponding integer value. Golang provides two main methods for converting a string to an integer. Converting a string to an integer involves extracting the numerical value from the string and converting it to an integer.
In Golang, a string is a sequence of characters, and an integer is a numerical value.
