Floating Point Issues

PYTHON CODE

sum = 0 toAdd = .1 max = int(input("The number of iterations: ")) for i in range (0, max, 1): sum = sum + toAdd print(sum, i)

print("Number of iterations: ", max) print("Number added: ", toAdd) print("Calculated sum: ", sum) print("Difference between correct sum and calculated sum: ", (max * toAdd - sum))

One potential solution - Python

- Import the decimal package to the above-given code

- ADD to your file a second loop that does exactly the same as the first loop but now using a decimal number repeatedly. You will have to make sure that all operations are done using decimals

- How does the error behave as you run the code for 10, 100, and 1000 iterations? Is it better or worse than using Pythons default floating datatype

- Do some research on the decimal module, and figure out the reason for the result
