Compared to Alternatives

amounts does not replace every other library. It draws a different boundary.

Compared to money

money is stronger when you want a mature fiat-money ecosystem with currency metadata and exchange helpers.

amounts is stronger when you want:

• arbitrary-precision atomic storage as the primary model
• crypto-scale decimals
• one abstraction spanning money, tokens, commodities, inventory, and points

Compared to ruby-units or measured

Those libraries are stronger for physical dimensions and unit systems.

amounts is stronger when the core question is “how much of this fungible thing do I have?” rather than “how do physical units convert and compose?”
