## About the changes
According to our docs, we only support up to 1 decimal place for
weights. This is to use integers to represent the percentages (we divide
them by 10) and supporting more decimals results in bad maths due to
floating point arithmetics.
This PRs adds Frontend and Backend validations to enforce this
restriction
Closes#2222
## Discussion points
Should we reconsider supporting more decimal places, that door remains
open, but for now we'll just adhere to our documentation because that
change would require some development.
