The tax calculator program of the case study outputs a floating-point number that might show more than two digits of precision.
Aneli [31]

Answer:

TAX_RATE = 0.20

STANDART_DEDUCTION = 10000.0

DEPENDENT_DEDUCTION = 3000.0

gross_income = float(input("Enter the gross income: "))

number_of_dependents = int(input("Enter the number of dependents: "))

income = gross_income - STANDART_DEDUCTION - (DEPENDENT_DEDUCTION * number_of_dependents)

tax = income * TAX_RATE

print ("The income tax is $" + str(round(tax, 2)))

Explanation:

Define the <em>constants</em>

Ask user to enter the <em>gross income</em> and <em>number of dependents</em>

Calculate the <em>income</em> using formula (income = gross_income - STANDART_DEDUCTION - (DEPENDENT_DEDUCTION * number_of_dependents))

Calculate the <em>tax</em>

Print the <em>tax</em>

<em />

round(number, number of digits) -> This is the general usage of the <em>round</em> function in Python.

Since we need <u>two digits of precision</u>, we need to modify the program as str(<u>round(incomeTax, 2</u>)).

The FROM command signifies the location.

ORDER BY command ensures that your result is ordered

ASC means Ascending Order.

; signifies the end of the query.
