Python math Module
🧮 Python math Module
Python math Module is a built-in module that deals with all the mathematical functions and calculations. The math module in Python provides access to mathematical functions defined by the C standard. It includes functions for:
- Arithmetic operations
- Trigonometry
- Logarithms
- Constants like π and e
- Rounding and power functions
To use the module, you must first import it.You can import the module into your program by using the following line:
import math
math Functions
Some of the functions in the math module are as follows:
- math.sqrt(256)
- math.pi
- math.sin(math/pi/3)
- math.factorial(9)
- math.floor(12.79)
- math.pow(3,4)
