Notes
Math Module
Math module in python is a module used to do all kinds of mathematical operations.
import math
Ceil Function
Return the smallest integer greater than or equal to the number.
math.ceil(3.5)
# Output is 4
Exponent Fuction
Returns e raised to the power of specified argument.
math.exp(3)
# Output is 20.085536923187668
Fabs Function
This function is used to find the absolute (mod value) of any number.
math.fabs(-2.303)
# Output is 2.303
Floor Function
This function is used to get the largest integer greater than or equal to a given number.
math.floor(4.3034)
# Output is 4
Log Function
This function is used to find logarithmic value of any number to any base.
math.log(12,11) #math.log(number,base)
# Output is 1.0362865626271018
Sine Function
This function is used to find the sine of any number.
math.sin(math.pi) # Argument always in radians
# Output is 1.2246467991473532e-16
Cos Function
This function is used to find the cosine value of any number.
math.cos(math.pi)
# Output is -1.0
Degrees Function
This function is used to convert angle which is in degrees to radians.
math.degrees(math.pi)
# Output is 180
Radians Function
This function is used to convert angles in radians to angles in radians.
math.radians(180)
# Output is 3.141592653589793
Fmod Function
This function returns the modulus (remainder) resulting from division of x from y
Diffrence between x%y and math.fmod(x,y)
It is important to note here that x%y return mod value with lesser precision which has the sign of y while math.fmod(x,y) has more precision and returns answer according to the sign of x.
math.fmod(-9,2)
# Output is -1
(-9)%2
#Output is 1
Factorial Function
This function is used to find the factorial of specified integer.
math.factorial(5)
# Output is 120
GCD Function
This function is used to find the Greatest Common Divisor of two numbers.
math.gcd(5,10)
# Output is 5
