The output should be descending from 100 to 0 . The Math module in Python comes pre-defined with some of the most useful mathematical functions. After importing it, we can use to call this function using the static object. As probability exists in the value range of 0 to 1, hence the range of sigmoid is also from 0 to 1, both inclusive. We take a simple example and in this example will tell you how to import the Math module of Python into your Python program: 1 2 3 4 5 6 import math x = math.sqrt (4) print(x) In the example given above, we imported the math module and also used the sqrt () method of the math module. Python provides math functions in the math module. Syntax: math.log(x, base) Parameters: x: This is required. However, the math module does not support complex data types. (Contributed by Serhiy Storchaka in bpo-37295.) This operator is basic, and it is limited for calculation. Functions help break our program into smaller and modular chunks. Python also makes use of functions to improve modularity of the program. Number-theoretic and representation functions math.ceil(x) Return the ceiling of x, the smallest integer greater than or equal to x . Suppose, if we want to define the particular function, f (x) = (e^x - 1)/x, then we can use math e constant to achieve that. Prints the result on the screen. Python Program for log() Function Read More Math is a built-in module in Python that adds to the set of mathematical functions. The idea is to put some commonly or repeatedly done tasks together and make a function so that instead of writing the same code again and again for different inputs, we can do the function calls to reuse code contained in it over and over again. Syntax math.sqrt (x) Parameter x - that can be any value. Replaces none-ascii characters with escape character. Python math Python math is a built-in standard module used to work with complex scientific calculations. Furthermore, it avoids repetition and makes the code reusable.
