Need help with a Custom empty? function
I have this sample data structure below.
It is considered not empty if any of it’s Decimal values is greater than decimal<0>
Please how would you check for that?
My code below incorrectly returns false, when it should return true:
def empty?(data) do
if Enum.empty?(data) do
true
else
Enum.any?(data, fn x ->
Decimal.decimal?(x) && !(Decimal.cmp(x, Decimal.new(0)) == :eq)
end)
end
end
data = %{"10100" => [{{1, 1, "employer-issuer-code"}, "PEC000000000000"}, {{1, 2, "instrument-code"}, "OTH20000000"}, {{1, 3, "instrument-rating"}, "00"}, {{1, 4, "coupon-rate"}, #Decimal<0.00>}, {{1,

I’ll accept sharp in lieu of hostile.
