This tutorial will learn how to round to two decimals in Python using ** round()** and

**methods.**

`format()`

## Round to two decimals in Python

When you deal with mathematical calculations in **Numpy **or Python, you will often get a lot of decimal values during the calculation. There are 2 ways to **round off the decimals in Python.** Let us take a look at both approaches in detail.

## Using round() Method

The ** round()** method returns the floating-point number, the rounded version of a specified number with the specified number of decimals.

**Syntax – round(number, ndigits)**

**number**– the number to be rounded, can be an integer, decimal/floating.**ndigits (optional**) – number of decimals to use when rounding the number. The default value is 0.

**Example – Round to two decimal places**

```
# integer round off
print("Integer round off Mid value ",round(7))
# Python code to round off floating number using default value
print("Floating round off ",round(7.7))
# Python code to round off floating number with mid value
print("Floating round off Mid value ",round(7.5))
# floating number round to two decimal places
distance= 4.3847594892369461
print ("The total distance is ", round(distance,2))
```

**Output**

```
Integer round off Mid value 7
Floating round off 8
Floating round off Mid value 8
The total distance is 4.38
```

**Note: **The behavior of round() for floats can be surprising: for example, round(2.675, 2) gives 2.67 instead of the expected 2.68. This is not a bug: it’s a result of the fact that most decimal fractions can’t be represented exactly as a float. See Floating Point Arithmetic: Issues and Limitations for more information.

## Using format() method

You can use the ** format() **method to handle the precision of the floating-point numbers, and there are many ways to set the precision of the number in Python.

**Syntax – string.format(value)**

- : introduces the format spec
- 0 enables sign-aware zero-padding for numeric types
- .2 sets the precision to 2
- f displays the number as a fixed-point number

Alternatively, **Using “ %”:- **“

**%**

” operator is used to format as well as set precision in Python.```
# Python code to round to two decimals using format
# initializing value
distance= 4.7287543
# using format() to print value with 2 decimal places
print ("The value of number till 2 decimal place(using format()) is : ",end="")
print ("{0:.2f}".format(distance))
# using "%" to print value with 2 decimal places
print ("The value of number till 2 decimal place(using %) is : ",end="")
print ('%.2f'%distance)
```

**Output**

```
The value of number with 2 decimal place(using format()) is : 4.73
The value of number with 2 decimal place(using %) is : 4.73
```
