Hello,
I have found 'devaluate' in some Spad files and it can be handy. Some
domains are parameterized and it is not possible, or at least I don't
know how to do it, to use ' is ' instead of ' has ' (Domain vs.
Category) for them:
if R is Foo then
new(n) == bar(n)
else
new...
it is not possible to use:
if Foo(p) then
Or like #1 in "SubDomain(Integer, #1 >= 0)" used for NonNegativeInteger?
I'm not sure I understand your problem 100%, are you looking for
something like PrimeField in ffdoms.spad?
if not prime?(p)$IntegerPrimesPackage(Integer) then
Also it's difficult to know your problem with 'devaluate' in your
code snippet. Is there a minimal reproducible example?
