Hi @sblessing,

We have an RFC process for additions and changes to the language and standard library.

BIgDecimal is basically F128 and BigInteger U128 and I128
I prefer F128, U128, I128

@cindRoberta BigInteger and BigDecimal are arbitrary precision integers, so they can be as big as you want as long as you have the memory to spare.

@ergl it looks the arbitrary bit-width integers from Zig: https://ziglang.org/documentation/0.8.0/#Primitive-Types

it's a good proposal, but no with the names BigDecimal and BigInteger
