Example Usage

1. Calculating the Square Root

Calculate the square root of a number using math.sqrt:

import math

result = math.sqrt(25)
print(result)  # Output: 5.0

2. Rounding Up with `ceil`

Round a floating-point number up to the nearest integer:

result = math.ceil(4.7)
print(result)  # Output: 5

3. Rounding Down with `floor`

Round a floating-point number down to the nearest integer:

result = math.floor(4.7)
print(result)  # Output: 4

4. Trigonometric Functions

Calculate the sine of an angle (in radians):

angle = math.radians(30)  # Converting degrees to radians
result = math.sin(angle)
print(result)  # Output: 0.49999999999999994

5. Exponential Function

Calculate the exponential of a number:

result = math.exp(2)
print(result)  # Output: 7.3890560989306495

6. Logarithmic Functions

Calculate the natural logarithm:

result = math.log(7.3890560989306495)
print(result)  # Output: 2.0

7. Factorial

result = math.factorial(5)
print(result)  # Output: 120

8. Greatest Common Divisor (GCD)

Find the greatest common divisor of two numbers:

result = math.gcd(60, 48)
print(result)  # Output: 12

9. Power Function

Raise a number to a given power:

result = math.pow(2, 3)
print(result)  # Output: 8.0

10. Constants

Access mathematical constants like (\pi):

pi_value = math.pi
print(pi_value)  # Output: 3.141592653589793
