Kotlin number to string format

Kotlin – Convert integer to string

In this tutorial, you shall learn how to convert an integer value to a string value in Kotlin, using Int.toString() function, with example programs.

Kotlin – Convert integer to string

To convert an integer number to string in Kotlin, we can use Int.toString() method.

Steps to convert an integer to a string

1. Consider that we are given an integer value n .
2. Call the toString() method on the integer n , and the function returns a string value created from this integer.

Example

In the following program, we read a number n from user and reverse it using the above steps.

Enter an integer : 52413 String value : 52413

Conclusion

In this Kotlin Tutorial, we learned how to convert a given integer to a string using Int.toString() method.

Kotlin String format() method example

Kotlin borrows the String.format() method from the Java language, so you can format your string values with it.

For example, suppose you want to format the PI value into a two-digit format ( 3.14 )

Here’s how you can format the digits:

Like in Java, the first argument of the format() function will be the string format, while the rest would be the values to put into the string.

The %f inside the string is used to format a floating value. The .2 is added to limit the floating-point to 2 digits.

If you want to pass a String value to the format, you can use the %s specifier as follows:

• %b — Boolean
• %c — Character
• %d — Signed Integer
• %e — Float in Scientific Notation
• %f — Float in Decimal Format
• %g — Float in Decimal or Scientific Notation, depending on the value
• %h — Hashcode of the supplied argument
• %n — Newline separator
• %o — Octal Integer (base 8)
• %s — String
• %t — Date or Time
• %x — Hexadecimal Integer (base 16)

You can use as many specifiers as you need in your String.format() method.

Here’s an example of using 3 specifiers in the string format (a Boolean , a String , and an Integer ):

Kotlin will run the formatter from left to right, taking the second argument as the first value for the string format and so on.

And that’s how you can format string values using Kotlin String.format() method 👍

How to Convert an Integer to String in Kotlin

Kotlin is a statically typed programming language developed by JetBrains. It is a modern language used for developing applications with a focus on safety, clarity, and conciseness. One of the most common tasks in programming is converting data types. In this post, we’ll look at how to convert an Integer to a String in Kotlin.

What is an Integer

An Integer is a data type that stores whole numbers. It is one of the primitive data types in programming, and it is used to represent a whole number with no decimal point. Integers are usually represented by 4 bytes (32 bits) of memory. This means that an Integer can store a value up to 2^32-1.

What is a String

A String is a data type that stores text. It is a sequence of characters that can be used to represent words, numbers, and symbols. Strings are usually represented by an array of bytes, and they can store a value up to 2^32-1.

Converting an Integer to a String

Now that we know what an Integer and a String are, let’s look at how to convert an Integer to a String in Kotlin. There are two ways to do this: using the toString() method or using string interpolation.

Using the toString() Method

The toString() method is a built-in Kotlin function that converts an Integer to a String. It takes an Integer as an argument and returns a String. To use it, simply pass the Integer to the toString() method.

// Integer to convert val number = 42 // Convert Integer to String val str = number.toString() // Print the String println(str) 

The above code will print 42 in the console.

Using String Interpolation

String interpolation is a feature of Kotlin that allows you to insert variables directly into a string. It is a simpler and more concise way of converting an Integer to a String. To use it, simply use the $ symbol followed by the Integer.

// Integer to convert val number = 42 // Convert Integer to String val str = "$number" // Print the String println(str) 

The above code will also print 42 in the console.

Conclusion

In this post, we looked at how to convert an Integer to a String in Kotlin. We saw two ways to do this: using the toString() method or using string interpolation. Both of these methods are simple and straightforward, so choose the one that best fits your needs.
