How to Round number in PythonPython provides the builtin round() function, which used to round off a number to a given number of digits. It takes the two arguments, first is n, second is n digits and then it returns number n after rounding it to ndigits. By default, it rounds off the number n to the nearest integer. For example  If we want to round off a number, let's suppose 7.5. It will be rounded off to the nearest whole number is 7. However, the number 7.56 will be rounded off to 7.5 by one places to give. The round() function is essential when working with the number of floats that may have many decimal places. The round() function makes easy and simple. The syntax is given below. Syntax:The parameters are 
Let's understand the following example  Example Output: 15 26 25 Now, the second parameter is used. Example Output: 25.47 25.428 25.42 The reallife example of the round() functionThe round() function is most useful while changing fractions to decimals. We generally get the number of a decimal points such as if we do 1/3 then we get 0.333333334, but we use either two or three digits to the right of the decimal points. Let's understand the following example. Example  Output: 0.16666666666666666 0.17 Another example Example  Output: 6 5 6 The round() function rounds 5.5 up to 6 and 6.5 down to 6. This is not a bug, the round() behaves like this way.
