We can pass a number value as a Nuber() constructor parameter in the number or string format. The value of the numberValue variable is 124354656Ī Number is an object in TypeScript, and we can use it as a constructor to create an instance of the Number object. The above code will produce the following output – The type of numberValue variable is number On compiling, it will generate the following JavaScript code − var stringNmber = "124354656" let stringNmber: string = "124354656" Ĭonsole.log("The type of numberValue variable is " + typeof numberValue) Ĭonsole.log("The value of the numberValue variable is " + numberValue) In the output, users can observe that type of the numberValue variable is number. Afterward, we used the unary ‘+’ operator to convert the stringNumber string value to the number and stored the evaluated value in the numberValue variable to the number data type. In this example, the stringNumber variable contains the number value in the string format. In the above syntax, we have used the stringNumber variable as an operand of the unary ‘+’ operator. Users can follow the syntax below to convert the string to a number value. So, we can use it to convert strings to numeric values. Before evaluating an operand, it converts the operand to the number value. The unary operator takes a single operand. So, we require to convert the string to a number in TypeScript. We will learn to convert strings to numeric values using various methods and approaches in TypeScript. For example, adding another number value to the string of numbers appends the number to the string rather than adding. If we perform the mathematical operation on the string values, it gives weird results. Sometimes, we get the number in the string format, and we need to convert the string values to the number to perform mathematical operations on the value. The Below example converts valid and invalid values to String.The string and number are both primitive data types in TypeScript. In this case, the typeof method checks the value type and returns the primitive type as a string. In typescript, + is an operator used to append the string. This is an easy and simple way to parse a number into a string.įor example, given number values are 11,13, add an empty string and return a string object.

How to Convert Number to String in Typescript examples ![]() ![]() For conversion to number, a String must contain only numbers. The number to String and String to Number conversions are some of the simple tasks of typescript developers. ![]() The number represents numeric values, whereas String represents a group of characters surrounded in double or single quotesīecause the integer type does not automatically convert to the String type, developers have to write code that performs the manual conversion. ![]() These are already known to every developer.Įvery developer is already aware of these types. In the typescript programming language, the fundamental datatypes Number and `String“ are basic Inbuilt primitive datatypes. Many situations originated during the development of angular/typescript-based projects as a result of writing this blog post.
