![]() ![]() Here in my above example, I am using Locale.US local. However you shouldn’t depend on the default locale, try to specify one instead. If you formatted it with NumberFormat, you should use NumberFormat.parse() to parse it back. NumberFormat can be locale-aware (in your example it uses the default locale for your computer) or you can explicitly specify format patterns, whereas the parseXXX() methods of Number subclasses only read “plain” numbers (optional minus sign+digits). Mixing NumberFormat and Long.parseLong() isn’t a good idea always. NumberFormat format = NumberFormat.getInstance(Locale.US) Long result2 = Long.valueOf(bumber2.replaceAll(",", "").toString()) remove all commas and then converting to long This class provides several methods to convert a long to a String and a String to a long, as well as other utility methods. It is essential to know at least three of them when working in JavaScript as they sometimes come in very handy, enhancing the flexibility and usability of your code.The class wraps a value of the primitive type long in an object. In this article, we discussed various techniques to convert a number to a string in JavaScript. You can now check t another tutorial if you are curious about how to convert string to number. ![]() One can choose the method that best suits the needs according to these factors. Decimal Precision: If you need to control the number of decimal places, the toFixed() method is a suitable choice.Readability: String interpolation and concatenation with an empty string are highly readable and make the code more expressive.Performance: Concatenation with an empty string and template strings tend to be faster and hence show better performance.We have to consider the specific requirements of a project while choosing a method for conversion. Note that toFixed() returns a string representation of the number, not a rounded number value. We rounded down the floating point number to 2 decimal places by passing 2 as a parameter in the toFixed() function and finally stored the string obtained from the function in a variable. We have used the toFixed() method to convert a floating point number to a string. Num: variable representing the number that has to be converted to stringĭecimal_places: a number that represents the decimal places by which the floating point number has to be rounded. Syntax of toFixed() Function is as follows: let convertedStr = num.toFixed(decimal_places)ĬonvertedStr: variable to store the string that we get from the toFixed() function. This method rounds the number to the specified precision and returns it as a string. But, this method is primarily used when you need to convert a number to a string with a specific number of decimal places. The toFixed() method is another method of converting a number to a string. The method works with both integers and floating-point numbers. printing and checking type of convertedStr variableĬonsole.log(convertedStr + " " + typeof(convertedStr)) ![]() ![]() printing and checking the type of numFloat variableĬonsole.log(numFloat + " " + typeof(numFloat)) Let us understand with the help of an example. The String() parameter would simply convert the number to a string in whichever form it is passed. The difference between the toString() function and the String() constructor is that the toString() method can convert the number into different decimal forms and then to a string, i.e. It takes any value or variable as the parameter and converts it into a string. String() is a constructor of the class String. We passed various radices and stored the obtained strings in different variables which are printed on the console. In this example, we have used the toString() function to convert the number 9 to a string. printing and checking type of convertedStr variablesĬonsole.log(convertedStrBin + " " + typeof(convertedStrBin)) Ĭonsole.log(convertedStrOct + " " + typeof(convertedStrOct)) Ĭonsole.log(convertedStrDec + " " + typeof(convertedStrDec)) Ĭonsole.log(convertedStrHex + " " + typeof(convertedStrHex)) using the toString() method with different radices printing and checking the type of num variable ![]()
