Seven Python Math Library Functions 🧮 🐍

A beginner should know about these important functions, it will make your work easy!!

Thread 😁🧵

1⃣ 𝘀𝗾𝗿𝘁

In python, to find the square root of any number ( 3 is the square root of 9 ) you don't have to use power operator.

There is a special function " sqrt " which square roots the number given it as a parameter :)

🔗 Code

2⃣ 𝗽𝗼𝘄

In the above tweet, we have learned how to square root a given number.

A square root is actually a number raised to a power of 0.5

But what if we want 3 or something as power.

Here we use " pow(x,y) " it returns x raised to power y.

3⃣ 𝗰𝗲𝗶𝗹

ceil function in python is used to return the smallest integer greater than equal to the given number.

For ex- ceil(9.1) = 10 , ceil(9.0) = 9

🔗Code

4⃣ 𝗳𝗹𝗼𝗼𝗿

floor function in python returns the largest integer smaller than or equal to the given number.

For ex- floor(9.9) = 9 , floor(9.1) = 9

🔗 Code

5⃣ 𝗳𝗮𝗰𝘁𝗼𝗿𝗶𝗮𝗹

Yes, you read it correctly!!

You don't have to write a program for finding the factorial of a number.

It's just one line of code ;)

🔗 Code

6⃣ 𝗶𝘀𝗻𝗮𝗻

While doing analysis of data of 1000s of entries, sometimes we have to check that which entry is empty or NaN ( Not a number)

To check this math library have " isnan " function.

It returns true if x is a NaN otherwise returns False!

🔗 Code

7⃣ 𝗲𝘅𝗽

In mathematical calculations, sometimes we have to find exponential of some number.

Don't worry you don't have to do calculations in python ;)

There is a simple function exp, which take number as input and gives the result!!

🔗Code
