Hi Pythonistas!,

While working with numbers where we need more precision like financial/ scientific values float cannot be a better option due to rounding errors. Today we are going to learn a package called **fractions**. The built-in fractions module provides a powerful toolkit for handling rational numbers, allowing you to maintain precision and accuracy in your calculations. Let's dive into the code

**Creating Fractions**

```
from fractions import Fraction
a = Fraction(3, 4)
print(a)
b = Fraction(1, 2)
print(b)
c = Fraction(2, 4)
print(c)
```

**Output**

```
3/4
1/2
1/2
```

**Note**: fractions module does the simplification of the fraction during the creation. If we check 2/4 converted into 1/2

**Converting Floats to Fractions**

```
a = Fraction(0.75)
print(a)
```

**Output**

`3/4`

**Converting Fractions to Floats**

```
a = Fraction(3, 4)
print(float(a))
```

**Output**

`0.75`

**Note**: This may lead to rounding errors

**Performing arithmetic operations**

```
a = Fraction(3, 4)
b = Fraction(1, 2)
print("Sum: ", a+b)
print("Product", a*b)
print("Difference", a-b)
print("Division", a/b)
```

**Output**

```
Sum: 5/4
Product 3/8
Difference 1/4
Division 3/2
```

The **fractions** module is a powerful tool for scenarios where you need precise and exact numerical representations. It can be precious in fields that require accurate calculations and in situations where fractions are a natural and meaningful way to express values.
