## Introduction

In this tutorial, you’ll learn how to convert float to int in Python.

As you might already know, in order to convert a float to an int, you can use the int() function. However, you’ll need to be careful when using this function as it can lead to unexpected results.

Specifically, if you try to convert a floating-point number that is too large or too small, you’ll get an overflow error. Additionally, if you try to convert a non-numeric string (e.g., “hello”), you’ll get a ValueError.

To avoid these errors, you can use the math module’s floor() and ceil() functions. These functions will round down and round up, respectively, to the nearest integer.

Alternatively, if you’re working with whole numbers (i.e., numbers without fractional parts), you can use the int() function’s third argument, known as the base. By specifying a base of 2, 8, or 16, you can convert a float to its binary, octal, or hexadecimal representation.

## What is a Float?

In computer science, a float is a data type composed of a number that is not an integer. Float values are typically used to represent non-integer values such as 3.14159 or 2.71828. In most programming languages, floats are represented using a finite set of bits, so they can only approximate real numbers. As a result, floats are often used for scientific or technical calculations where precision is important.

Integers, on the other hand, are data types composed of a number that is an integer. Unlike floats, integers can represent both positive and negative values. Integer values are typically used to represent whole numbers such as 1, 2, or 3. In most programming languages, integers are represented using a finite set of bits, so they can only approximate integers. As a result, integers are often used for counting or measuring purposes where precision is not as important.

So how do you convert a float to an int in Python? The easiest way is to use the built-in int() function. This function takes a float value and converts it to an int value by truncating the decimal part of the float value. For example:

“`
>>>int(3.14159)
3
>>>int(-2.71828)
-2
“`

## What is an Int?

An int is a data type used to represent whole numbers. A float is a data type used to represent decimal values. When we convert a float to an int, we cut off the decimal part of the number. For example, if we have a float with the value 3.14 and convert it to an int, we will end up with an int with the value 3.

## Why Convert Float to Int?

There are a few reasons why you might want to convert a float to an int in Python. Maybe you’re reading in data from a file, and the data is stored as floats. Or maybe you’re doing some mathematical operations on floats, and you want to round the results to integers.

Whatever the reason, it’s easy to convert floats to ints in Python. You can use the built-in int() function, or you can use math.floor() or math.ceil() from the math module.

Here’s a quick example of how to convert a float to an int in Python:

“`python
float_num = 3.14
int_num = int(float_num)
print(int_num) # prints 3
“`

## How to Convert Float to Int in Python?

There are many ways to convert a float to an int in Python. The most common way is to use the built-in int () function. You can also use the math.trunc () or math.floor () methods. If you want more control over the conversion, you can use the decimal.Decimal class or the fractions.Fraction class.

## Examples

floats can be turned into integers by using the int() function. For example, if you have a float variable called num, you can print its value as an integer using int(num).You can also convert strings to integers by using the int() function followed by the string variable that you want to convert.

In some cases, you will want to round a float to an integer. This can be done by using the Python built-in function round(). The round() function takes two arguments: the float to be rounded and the number of decimal places to round it to. For example, if you have a float variable called num and you want to round it to two decimal places, you would use round(num, 2).
