Math Functions & Math Modules

Math Functions

We will start with basic math functions

Round function

Absolute function: Always reply with a positive value

Math module: separate files with some reusable codes

We use it to organize  our code into different files

math ceiling:

math floor

Different math modules:

math.ceil(x)

Return the ceiling of x, the smallest integer greater than or equal to x. If x is not a float, delegates to x.__ceil__(), which should return an Integral value.

math.copysign(x, y)

Return a float with the magnitude (absolute value) of x but the sign of y. On platforms that support signed zeros, copysign(1.0, -0.0) returns -1.0.

math.fabs(x)

Return the absolute value of x.

math.factorial(x)

Return x factorial. Raises ValueError if x is not integral or is negative.

math.floor(x)

Return the floor of x, the largest integer less than or equal to x. If x is not a float, delegates to x.__floor__(), which should return an Integral value.
