The round() function in Python is used to round off a given number to a specified number of digits. It takes two arguments, the first being the number to be rounded and the second being the number of digits to round to. If the second argument is not provided, the function rounds the number to the nearest integer. The function uses the standard rounding rules, where numbers ending in 5 are rounded up if the preceding digit is odd and rounded down if the preceding digit is even. The function returns a float if the second argument is provided, otherwise it returns an integer. Keep reading below to learn how to python round in Kotlin.

Python ’round’ in Kotlin With Example Code
Python’s `round()` function is a commonly used function to round off a floating-point number to a specified number of decimal places. Kotlin, being a modern programming language, also provides a similar function to round off numbers. In this blog post, we will discuss how to use the `round()` function in Kotlin.
The `round()` function in Kotlin is a member function of the `Double` class. It takes an optional argument that specifies the number of decimal places to round off to. If no argument is provided, it rounds off to the nearest integer.
Here’s an example of how to use the `round()` function in Kotlin:
val num = 3.14159
val roundedNum = num.round(2)
println(roundedNum) // Output: 3.14
In the above example, we have a floating-point number `num` with the value `3.14159`. We then call the `round()` function on this number with an argument of `2`, which specifies that we want to round off to two decimal places. The result is stored in the `roundedNum` variable, which is then printed to the console.
If we don’t provide an argument to the `round()` function, it rounds off to the nearest integer. Here’s an example:
val num = 3.6
val roundedNum = num.round()
println(roundedNum) // Output: 4.0
In the above example, we have a floating-point number `num` with the value `3.6`. We call the `round()` function on this number without any arguments, which means it will round off to the nearest integer. The result is stored in the `roundedNum` variable, which is then printed to the console.
In conclusion, the `round()` function in Kotlin is a useful function to round off floating-point numbers to a specified number of decimal places or to the nearest integer. It is a member function of the `Double` class and takes an optional argument to specify the number of decimal places to round off to.
Equivalent of Python round in Kotlin
In conclusion, the equivalent function to Python’s round() in Kotlin is the round() function. This function takes in a floating-point number and returns the closest integer value. Additionally, the round() function in Kotlin also has an optional second parameter that allows you to specify the number of decimal places to round to. This can be useful in situations where you need to round a number to a specific precision. Overall, the round() function in Kotlin is a powerful tool for working with floating-point numbers and can help you achieve accurate and precise calculations in your Kotlin programs.
