# How To Do Math With Lists in python ?

We  not only use lists to store a collection of values, but we also use it to perform some mathematical calculations or operations to do.

## Example 1

import math
data = 21.6
print('The floor of 21.6 is:', math.floor(data))

## Output

The floor of 21.6 is: 21

## Example 2

cost = [0.424, 0.4221, 0.4185, 0.4132, 0.413]
cases = [10, 20, 30, 40, 50]
cost = [23, 10, 5, 32, 41]
weight= [10, 20, 30, 40, 50]
for i in range(len(cost)):
cost[c] = (cost[i] * weight[i] / sum(weight))
cost = sum(cost)
print(cost)

## Output

72.84444444444445

## Example 3

import math
degree = 180

print('The given angle is :', radian )



## Output

The given angle is : 3.141592653589793
sin(x) is : 1.2246467991473532e-16
cos(x) is : -1.0
tan(x) is : -1.2246467991473532e-16

## Following are the few Python Math Functions

• ceil(x):Returns the smallest integer value greater than or equal to x.
• copysign(x, y): Returns x with a sign of y
• fabs(x): Returns the absolute value of x
• factorial(x): Returns the factorial of x
• floor(x): Returns the largest integer less than or equal to x
• fmod(x, y): Returns a remainder when x is divided by y
• frexp(x): Returns a mantissa and exponent of x as the pair (m, e)
• fsum(iterable): Returns the accurate floating point sum of values in the iterable
• isfinite(x): Returns True if x is neither an infinity nor a NaN (Not a Number)
• isinf(x): Returns True if x is the positive or negative infinity
• isnan(x): Returns True if x is the NaN
• ldexp(x, i) : Returns x * (2**i)
• modf(x): Returns a fractional and integer parts of x
• trunc(x): Returns a truncated integer value of x
• exp(x) : Returns e**x
• expm1(x): Returns e**x – 1
• log(x[, base]): Returns the logarithm of x to the base (defaults to e)
• log1p(x) : Returns the natural logarithm of 1+x
• log2(x) : Returns the base-2 logarithm of x
