Quick SolutionTo Remove decimal places in Python, use

`int()`

function.

1234 a =3.2print(int(a))

Output3

Two of the most common types to represent numeric values are `int`

and `float`

. The `int`

type is used to represent a certain range of integers. The `float`

type represents values with fractional parts. The latter requires more memory and also represents a wider range than the `int`

type.

## Remove Decimal Places in Python

In this article, we will discuss how to remove decimal places in Python. For this, we will convert the `float`

values to an integer.

### Using the `int()`

function

The `int()`

function is used to typecast a value to an integer. To remove decimal places in Python we will pass a `float`

value with a decimal part to this function and it will remove decimal places in Python.

For example,

1 2 3 4 |
a =2.7 print(int(a)) |

**Output**

In the above example, we convert the `float`

value to an integer and the decimal places are discarded.

### Using the `math`

library

The `math`

library is used in Python to provide functions and constants that can calculate complex mathematical calculations. We can remove decimal places in Python using the `truncate()`

function from the `math`

library.

This function takes a `float`

value and removes the decimal part from the same, returning the integer value.

See the code below.

1 2 3 4 5 |
import math a =2.7 print(math.trunc(a)) |

Output:

We can also use the `floor()`

and `ceil()`

functions from this library. The former function returns the largest integer smaller than the given number and the latter returns the smallest integer greater than the provided value.

It will round off the `float`

value and return the calculated integer value.

For example,

1 2 3 4 5 6 |
import math a =2.7 print(math.floor(a)) print(math.ceil(a)) |

### Using string formatting

String formatting refers to the technique of getting the output string in our desired format. Using the `%d`

specifier we can get the output as an integer.

There are three ways in which we can use this format. The first method is by using the `%`

formatting where we specify the format along with the variable.

See the code below.

1 2 3 4 |
a =2.7 print('%d'%a) |

**Output:**

### Using the `round()`

function

We can also use the `round()`

function order to round the `float`

value to the required integer and remove decimal places in Python.

See the code below.

1 2 3 4 |
a =2.7 print(round(a)) |

Please note that `round()`

will remove decimal places, but it will also round the number to nearest integer.

## Conclusion

To conclude this tutorial, we discussed several methods to remove decimal places in Python. For this, we converted the `float`

type values to an integer using several methods. In the first method, we used the `int`

function to typecast the float value. Then we used the `round()`

function which rounded off the given value to the nearest integer.

We also demonstrated the use of functions from the `math`

library. These were the `trunc()`

, `floor()`

, and `ceil()`

functions. In the final method, we discussed how to use string formatting to remove decimal places in Python.
