How do you round to 2 decimal places in Python?

Python's round() function requires two arguments. First is the number to be rounded. Second argument decides the number of decimal places to which it is rounded. To round the number to 2 decimals, give second argument as 2.

What is the difference between the round () function and the INT () function?

The INT function returns a number without the decimal places. The TRUNC functions cuts off the number at two digits, while the ROUND function rounds the number to two digits. The TRUNC and ROUND functions returned a different result because the ROUND function returned a number where the decimal was rounded up.

How do you use the round function?

You can use the ROUND function in excel for rounding numbers to a specified level of precision. ROUND can be used for rounding to the right or left of the decimal point. If num_digits is greater than 0, the number will be rounded to the specified decimal places to the right of the decimal point.

Can you round a string in Python?

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.

How do you round up in Python 3?

Python has three ways to turn a floating-point value into a whole (integer) number:

1. The built-in round() function rounds values up and down.
2. The math. floor() function rounds down to the next full integer.
3. The math. ceil() function rounds up to the next full integer.

How do you round to 2 decimal places?

Rounding to decimal places

1. look at the first digit after the decimal point if rounding to one decimal place or the second digit for two decimal places.
2. draw a vertical line to the right of the place value digit that is required.
3. look at the next digit.
4. if it's 5 or more, increase the previous digit by one.

What is .2f in Python?

The format() method of formatting string is quite new and was introduced in Python 2.6 . ... 2f are called as format specifiers, they begin with % followed by character that represents the data type. For e.g %d format specifier is a placeholder for a integer, similarly %. 2f is a placeholder for floating point number.

What does correct to 2 decimal places mean?

“Two decimal places” is the same as “the nearest hundredth”. ... So, for example, if you are asked to round 3.264 to two decimal places it means the same as if your are asked to round 3.264 to the nearest hundredth. Some questions, like the example below, will ask you to “show your answer correct to two decimal places."

Does INT () round up or down?

INT rounds a number down using the Order rounding method. That is, it rounds a positive number down, towards zero, and a negative number down, away from zero. Therefore, it's easy to use INT to round a number up using the Math method.

Do ints round up or down C++?

Do ints round up or down Java?
