Remarks
The structure tries to approximate the value of FIRational(Decimal)
when creating a new instance by using a better algorithm than FreeImage does.
The structure implements the following operators: +, -, ++, --, ==, != , >, >==, <, <== and ~ (which switches nominator and denomiator).
The structure can be converted into all .NET standard types either implicit or explicit.
