Add numeric currency code by ISO 4217 standard

[letehaha]

Clear and concise description of the problem

Right now finance.currency has a structure of { code: 'USD', name: 'US Dollar', symbol: '$' }, but in many financial application I usually see numeric currency code usage, instead of string (so 840 instead of USD).

Suggested solution

The suggestion is to add numericCode (probably needs a better name) to the currency object inside faker.finance.

I can try to implement that by myself

Thank you for your feature proposal.

We marked it as "waiting for user interest" for now to gather some feedback from our community:

• If you would like to see this feature be implemented, please react to the description with an up-vote (:+1:).
• If you have a suggestion or want to point out some special cases that need to be considered, please leave a comment, so we are aware about them.

We would also like to hear about other community members' use cases for the feature to give us a better understanding of their potential implicit or explicit requirements.

We will start the implementation based on:

• the number of votes (:+1:) and comments
• the relevance for the ecosystem
• availability of alternatives and workarounds
• and the complexity of the requested feature

We do this because:

• There are plenty of languages/countries out there and we would like to ensure that every method can cover all or almost all of them.
• Every feature we add to faker has "costs" associated to it:
  • initial costs: design, implementation, reviews, documentation
  • running costs: awareness of the feature itself, more complex module structure, increased bundle size, more work during refactors

Team decision

This feature request seems reasonable. Due to the ISO standardization we accept it even tho the upvote number is comparativly low.

@letehaha Are you interested in implementing this?

[letehaha]

Thanks @xDivisionByZerox, I'll check this weekend what it requires and if I'll have time for it. Will keep you posted

[letehaha]

Hey @xDivisionByZerox, sorry but right now I have no capacity. I'll keep this in mind for the time I'm free, but no promises :)

[xDivisionByZerox]

@letehaha all good. I'll go ahead and open this issue for potential external contributions. Since the feature would follow an ISO standard, I even think this would be great for first-time contributors.

@xDivisionByZerox I have some time and I really like what you guys are working on. I'll look into this feature!
