Detailed explanation-1: -Round() Round() is a built-in function available with python. It will return you a float number that will be rounded to the decimal places which are given as input. If the decimal places to be rounded are not specified, it is considered as 0, and it will round to the nearest integer.
Detailed explanation-2: -The round() function returns a floating point number that is a rounded version of the specified number, with the specified number of decimals. The default number of decimals is 0, meaning that the function will return the nearest integer.
Detailed explanation-3: -What is the ROUND Function? The ROUND Function[1] is categorized under Excel Math and Trigonometry functions. The function will round up a number to a specified number of digits. Unlike the ROUNDUP and ROUNDDOWN functions, the ROUND function can round either up or down.
Detailed explanation-4: -In floating point arithmetic, two extra bits are used to the far right of the significand, called the guard and round bits. At the end of the arithmetic calculation, these bits are rounded off. We always round towards the closer digit (i.e. 0.00-‐0.49 → 0 and 0.51-‐0.99 → 1).
Detailed explanation-5: -Round, RoundDown, and RoundUp RoundDown always rounds down to the previous lower number, towards zero. RoundUp always rounds up to the next higher number, away from zero.
