Thus, we can state that the toFixed() method can convert a number into a string, as well as perform a rounding operation. It happens because this method accepts one optional parameter - the number of digits after the point that you want to keep. Note that all digits after the point are omitted in the string representation of the number. log( typeof string) // logs "string" console. The example of its use and the correct syntax are illustrated below. toString( 16)) // logs "-14" toFixed() and toExponential() methodsįor the situations when you need to specify the number of digits after the point, you can use another convenient method of the Number object. We see that it can convert a number into a string, as well as represent it in various number systems.
Convert int to string javascript code#
The code below illustrates different cases of using the toString() method and its arguments. It’s used in the situations when there is a need to explicitly specify the base of a number system (or radix) in which the value is represented. This method can accept one optional parameter. The syntax of the toString() method is simple: const number = 7 Ĭonsole. All the numbers in JS can be automatically transformed into a Number object which makes the use of its methods possible. JavaScript has a special object Number, which contains the toString() method allowing you to convert a number into a string. log( typeof value2) // logs "string" The toString() method
log( typeof value1) // logs "string" const value2 = $ // alternative way of casting value to string console. log( typeof value) // logs "number" const value1 = String(value) Ĭonsole. The code below illustrates the use of the String() function. After checking its type with the typeof() operator again, you can see that it turned into a string. Then, you can pass this value to the String() function and assign the result to the same variable. Using the typeof()operator you can check the type of the value. It accepts the numeric value as a parameter and returns its string representation.įor example, let’s create a variable and assign a numeric value to it. log( typeof string) // logs "string" The String() functionĪn alternate way to convert a number into a string is by using the built-in String() function. You can go further and use an empty string in order to convert a number itself without adding any text as illustrated in the example below. const number = 7 Ĭonst string = number + "days of the week" Ĭonsole.
Convert int to string javascript plus#
A plus operator added a string to this variable and thus, created a new string value which you can check using a typeof() operator. In the following code there is a variable of the number type. This way you can use concatenation for converting numbers into a string. For example 5+3 will return 53 instead of 8.
The process of adding one string to another using a simple plus operator will result in their joining instead of the actual mathematical operation. In JavaScript the word “concatenation” is used when talking about strings. One of the simplest ways to convert a numeric value into a string is by using concatenation which is the process of connecting one thing with another. There are several ways to transform a number into a string in JavaScript. There are situations when explicit conversion of the values is needed. For example, the alert() method will transform any passed value to a string without any additional actions by a programmer. In most cases operators and functions perform such conversions automatically. However, sometimes JS developers may face a need to convert the values from one type into another. JavaScript offers a powerful toolkit for working with various data types.
