Essentially the Money class stores the monetary value as a fixed scale (number of decimal places) decimal using the Fixed package. This allows for precise calculations as required when handling money and eliminates common rounding issues.
Let's start with some examples:
The package uses the following terms:
Minor Units  the smallest unit of a currency e.g. cents.
Major Units  the integer component of a currency  e.g. dollars
code  the currency code. e.g. USD
symbol  the currency symbol. e.g. '$'. It should be noted that not every currency has a symbol.
pattern  a pattern used to control parsing and the display format.
scale  the number of minor Units (e.g. cents) which should be used when storing the currency.
decimal separator  the character that separates the fraction part from the integer of a number e.g. '10.99'. This defaults to '.' but can be changed to ','
group separator  the character that is used to format thousands (e.g. 100,000). Defaults to ',' but can be changed to '.'
Note: Money2 has a maximum scale (decimals) and integer size of 18 digits. This is a somewhat arbitrary limit so raise a PR to fix the issue the help would be appreciated.
