As the algorithm performs division of numbers with high precision, it is very common to see really big numbers after the period (for example: 1200.2300001), which is not desirable because of several reasons: may cause confusion to some users when they see such big numbers; uses more memory to store a bigger number; it just does not make sense to display currency number in this format. For this reason, you are going to implement a utility function to format any number into the appropriate currency format, using 2 decimal places. For example: The number 1200.2300001 would be became: 1200.23

Question
As the algorithm performs division of numbers with high precision, it is very common to see really big numbers after the period (for example: 1200.2300001), which is not desirable because of several reasons:
may cause confusion to some users when they see such big numbers;
uses more memory to store a bigger number;
it just does not make sense to display currency number in this format.
For this reason, you are going to implement a utility function to format any number into the appropriate currency format, using 2 decimal places.
For example: The number 1200.2300001 would be became: 1200.23

"""This is an auxiliary function to format plain double
precision numbers into currency style.
:param value: the original value to be formatted
:param currency: the 3-digits country code to identify
the country's currency.
formatted_value = # formatted value
return # formatted value with 2 decimal places and
3-digits country currency code
