Yes decimal fields are now fully supported and send to the client side app connect in a special notation ending with ‘m’ to be recognized and threaten as decimals client side as well - this is the new upcoming JavaScript standard as well.
App Connect should pick up the new decimals and show and format them well.
Do note that just as with the new bigint (those end with ‘n’) all involved numbers in an expression should be of the same type!
So you can’t have:
22.44m + 1
But should be:
22.44m + 1m
That is why we also have formatters to convert to decimals and bigint now.
