# Currency Converter

## Problem Statement

The company ABC wants to build a currency converter.

Write a function that has the source currency amount, and exchange rate as parameters, and return the resulting target currency amount.

``Target currency amount = Source currency amount * Exchange rate``

## Input

The first line of input is a float number: `amount`, representing the amount of source currency.

The second line of input is a float number: `rate`, representing the rate of exchange from source currency to target currency.

## Output

Print the target currency amount.

## As is

The boilerplate code is already there to read the inputs from user, in the `main()` function, and to print the value returned by the `targetCurrencyAmount()` function. Do not edit this code.

## To do ✍

`targetCurrencyAmount()` has two parameters: `amount` and `rate`. Complete the function that calculates the target currency amount, and returns the same.

## Example 1

For the example, let us say we are converting Dollar to INR. And the input is `10` dollars with an exchange rate of `81.06`.

Test input

``````10
81.06``````

Test output

``810.6``

Explanation

For each dollar, we get 81.06INR. Therefore for 10 dollars, the converted value is `10 * 81.06 = 810.6`.

## Python Program

``````# Complete the following function
# Return target currency amount that's calculated
#     from amount, rate
def targetCurrencyAmount(amount, rate):

# Boilerplate code - Do not edit the following
def main():
amount = float(input())
rate = float(input())
# Print only last two digits
print("%.2f" % targetCurrencyAmount(amount, rate))

if __name__ == "__main__":
main()``````

Input and Outputs 1

``````9.5
78.80``````
``748.60``

Input and Outputs 2

``````21.03
0``````
``0.00``

Input and Outputs 3

``````56.16
79.99``````
``4492.24``

Input and Outputs 4

``````90.11
78.94``````
``7113.28``
``````# Complete the following function
def targetCurrencyAmount(amount, rate):
return amount * rate

# Boilerplate code - Do not edit the following
def main():
amount = float(input())
rate = float(input())
# Print only last two digits
print("%.2f" % targetCurrencyAmount(amount, rate))

if __name__ == "__main__":
main()``````
