In this shot, we will learn how to extract a float number's fractional part. 

# 
## 1. Using the modulo (`%`) operator
The **`%` operator** is an arithmetic operator that calculates and returns the remainder after the division of two numbers.

If a number is divided by 1, the remainder will be the fractional part. So, using the *modulo* operator will give the fractional part of a *float*.

## 
### Code 

decNum = 3.14159265359
frac = decNum % 1
print(frac)

## 2. Using `int()`

The function will round off the float to the nearest integer value.

After getting the integer part of the decimal number, we can take the difference between the original float and the integer number to find the fractional part.

### Code

decNum = 3.14159265359
frac = decNum - int(decNum)
print(frac)

In this example, `int(decNum)` returns 3, and subtracting it from 3.14(decNum) gives us the fractional part of the number, which is 0.14.

# 
## 3. Using `math.modf()`
To access the function `math.modf()`, we must first import the `math` module.

## 
##  Syntax
```
math.modf(float)
```

## 
##  Parameters

This function takes one parameter: 
- a float number.

###
### Return value
It returns the integer and fractional parts of `float` as a tuple, in that order.
If some data type other than `float` or `int` is passed, the function returns a TypeError.

###
### Code

import math

decNum = 3.14159265359
frac, intNum = math.modf(decNum)

print(frac)
print("TypeError raised: ")
math.modf("5")
