* \(1) First input must be an array, second input a scalar of the same type.
Output is an array of the same type as the inputs, and with the same values
as the first input, except for nulls replaced with the second input value.
-* \(2) Output is true iff the corresponding input element is non-null.
+* \(2) Output is true iff the corresponding input element is NaN according to
std::isnan(value).
