In Python there are many built-in functions and `abs()`

method is one of them. The main purpose of this function is to return the absolute value of the number(variable) passed as argument to it.

This is a detailed post on** **`abs()`

method that touches every aspect of it.

`abs()`

method:The `abs()`

method takes only one argument and hence the syntax is pretty simple,

```
# X can be an integer or a float or a complex number
abs(X)
```

If, **X (the argument)** is an Integer or Float then the method will return the absolute value in Integer or Float

else if **X **is a Complex Number then the method will return the magnitude of that complex number.

The absolute value for a given number is the numerical value of that number without considering whether the sign of the number is **positive (+ve) or negative (-ve )**.

Simply put, an absolute number is always a positive(+ve) number.

For complex numbers, the absolute value is their **magnitude**.

**Example for Integer:**

The absolute value of -5 is 5.

**Example for Float:**

The absolute value of -5.5 is 5.5

**Example for Complex Numbers:**

The absolute value of 3+4j is 5.0

Lets see, how to find the magnitude of a complex number,

The magnitude of complex number **a+bj **is** sqrt( a^2 + b^2 )**.

**For example: **The magnitude of 3+4j is **sqrt( 3^2 + 4^2 )** = sqrt( 9 + 16 ) = sqrt(25) = 5

`abs()`

FunctionBelow we have a simple program where we have used the `abs()`

method,

Pheww! This is it. I hope that you enjoyed the post and learned about the implementation of `abs()`

** **built-in function available in Python Standard Language. If you feel that this post is useful, please share it with your friends and colleagues.

Thanks for reading it till the end.
