BigDecimal type (500 Gold)

[mikera]

Convex maybe should support a native BigDecimal type

• Must build upon the BigInteger type
• Must support all integer numeric operations
• Must maintain a decimal point position (up to long capacity)
• Must have a strategy for ensuring values are canonical (e.g. always storing BigInteger with no trailing zeros)
• Must be an ACell for effective CVM usage

where can I find BigInteger code for reference?

Hi @geofflangenderfer - That's a separate bounty #4

Existing implementation exist for various fixed size numeric types, e.g. CVMDouble and CVMLong., which provide most of the boilerplate for arbitrary precision numeric classes. Also StringShort and StringTree show methods for handling arbitrary length objects on the CVM.

Probably best to jump on the Discord to discuss if you have ideas here! https://discord.com/invite/xfYGq4CT7v

I get no result searching for "StringShort" or "StringTree".

I'm still unsure where to:

• find reference material
• map that to bounty requirements

You would get more contributions if you make it easier to jump in.

Hi @geofflangenderfer , we'll be opening the main Convex repository for public access in a week or two.

If you'd like advance private access that is certainly possible - but please ping me on the Discord, I would like to discuss what you are keen to do and then I can also point you to the right materials.
