I guess we have already seen that sometimes you need decimal values in
representation tasks (money...). The list-readers who don't want
decimals also admit this when they show workarounds like valueInCents.

$valueInCents+tools, than simply providing decimal support? Why is it
less error prone and nicer to complicate things with those multiplied
values (force designers to always keep in mind, that what is 10.25 in
real-world, is 1025 here...), than simply use decimals? Does it make
