This is failing because we for some reason are MarshalJSON'ing decimals when used as parameter keys. That should be fixed in a separate PR. |

All this logic already exists using Decimal.String() - why are we not reusing it?

Oh woops, didn't see that lol

Actually I think this implementation is more efficient (albeit harder to grok). I'd actually propose making a follow-up issue to compare efficiencies via benchmarks and converge on using one or the other.

Yo - If I had to guess I'd say you're correct why don't we:
- Replace the
.String()code with your new updated logic - Use
.String()in JSON Marshalling here - copy the old code into a #postlaunch issue for later benchmarking
:)
how does that sound?

Is this R4R? |

Its ready to merge once I replace the current string implementation with my (more efficient looking) implementation written here. |

Closes #2475
This implementation has sub-optimal efficiency, should re-use memory allocations in unmarshalling. However this is only called for UI purports, so not really a big deal if its a tiny bit slower.
