Thanks for the PR! A few things:

A hard-coded replace(/,/, '.') is too fragile, we need a real locale-aware function. We already have some formatters in src/core/lib/numbers.ts , we probably would need to add a parser that accepts a value and a language code and write a little glue code.

Also, while I haven't tested it, but changing the column type in the weight table to string probably breaks the order because it now sorts lexicographically ("100" < "30" < "9")
