Problem Description
The following statement
ROW a=0 | EVAL b=CASE(a==0, 1.5, 2)
results in an error:
verification_exception - Found 1 problem
line 1:18: third argument of [CASE(a==0, 1.5, 2)] must be [double], found value [2] type [integer]
I'd expect implicit conversion to happen, comparable to C++'s implicit conversion.
Steps to Reproduce
ROW a=0 | EVAL b=CASE(a==0, 1.5, 2)
