Python math functions and modules

Python math functions and modules
Hi guys. Welcome to another session of python programming. If you are new here please do checkout our previous on python. Also check out our YouTube channel to get the full tutorial on this article.

In this session we are going to see the different math functions and modules in python.

Python has a variety of default functions which do not require any import module. Some of this predefined functions are: input(), int(), float(), type() and many others.

The syntax for this python math module and functions is given below

Python math functions and modules
Python math module

Python has an already default module known as math module which has a list of predefined functions to do mathematical calculations. To first work with this math module, we need an import statement:

 import math

Below is a list of table showing some math’s function

pow

math.pow(base,exp)

This function returns base raised to power exp.

Error occurs if (base=0 and exp<=0) or (base<0 and exp is not integer).

math.pow(8,2) gives 64

ceil

math.cell(num)

This function returns next integer value.

math.ceil(1.3) gives 2.0

math.ceil(-1.3) gives -1.0

floor

math.floor(num)

This function returns previous integer value.

math.floor(1.3) gives 1.0

math.ceil(-5.-3) gives -4

sqrt

math.sqrt(num)

This function returns the square root of a number. If number is less than 0, error will be shown.

math.sqrt(64.0) gives 8.0.

log10

math.log10(num)

log10() function returns the base 10 logarithm for num.

Error occurs if num <=0.

math.log10(1.0) give base 10 logarithm for 1.0.

sin

math.sin(arg)

sin() function returns the sine of arg. The value of arg must be in radians

math.sin(val)

(val is a number)

cos

math.cos(arg)

cos() function returns the cosine of arg. The value of arg must be in radians

math.cos(val)

(val is a number)

tan

math.tan(arg)

tan() function returns the tangent of arg. The value of arg must be in radians

math.tan(val)

(val is a number)

degrees

math.degrees(x)

degrees() converts angle x from radians to degrees.

math.degrees(478) would give 27,387.38

radians

math.radians(x)

radians() converts angle x from degrees to radians.

math.radians(14) would give. 0.244346

  • Pi has the mathematical value pi=3.141592.
  • Mathematical e has the mathematical value e=2.718281
  • The function in python are used directly
Below are some mathematical functions when they are executed in a shell

JavaScript Functions

  Hi there, and welcome to another exciting lesson on JavaScript. If this is your first time here, please do well to check out our previous lessons. In the previous lesson, we were discussing JavaScript math methods. It was very intuitive as we got to learn how to use the various math methods. To proceed, we shall be looking at JavaScript functions.  A function in JavaScript like in every other programming language could be defined as a block of code that is written to perform a particular task, and this function is usually invoked or called before it is being implemented. We have been talking about methods throughout the previous lessons right. Do you know that those methods are actually functions? Yes they are functions. You can now have an overview of the importance of functions in every programming language. How do we create a function in JS? To create a function, you follow the format function functionName(Argument) {//Block of code }. Some functions do have a return val...

JavaScript Math Methods

Hello everyone, and welcome to another exciting JavaScript lesson. In the last lessons you have been seeing other methods being used in JS (for example, the string methods). We shall go further into exploring other methods. This time, it’s going to be math methods. Do not move an inch because it’s going to be a very exciting. Before we look at what a math method is, let’s have an overview of math objects. A math object in JavaScript is a static built-in object that includes properties and methods used in performing mathematical tasks. Talking about math properties, they have the syntax Math.property . Some examples are Math.E that returns Euler’s number, Math.PI that returns PI, Math.LN2 that returns the natural logarithm of 2, and many others. The various JavaScript methods contained in the math object, thus, make mathematical operations easier and reduce effort as well as time in math-oriented programming. Some JS methods include abs( ), ceil( ), cos( ), sqrt( ), pow( ), log( ) ...

How to generate random numbers using NumP1

Hello. Welcome to another edition on this platform. For more better understanding, do checkout our YouTube channel to get the video tutorial. In this article of today, we are going to see how to generate random numbers using any of the following methods: Generating a random number Generating a random float and integer Generating random number arrays Generating random number from an array What is a random number? This is a number which cannot be predicted before its occurrence. This number might not different every time. Programmatically, they are two categories of random numbers:     Pseudo-Random numbers       True Random numbers. Just as programs which are written by programmers are a set of instructions, we must follow an algorithm to generate random numbers. Random numbers which are generated using an algorithm are called Pseudo-Random numbers. To generate a true random number, it is important to get the data from sources such as the keyboards, mou...
