Handling NULL attribute values
If an attribute value is missing for a record, then the attribute is referred to as being NULL. For example, if a record does not contain an assignment for a Price attribute, EQL defines the Price value as NULL.
Type promotion
In general, EQL performs type promotion when there is no risk of loss of information.
Handling of NaN, inf, and -inf results
Operations in EQL adhere to the conventions for Not a Number (NaN), inf, and -inf defined by the IEEE 7540 2008 standard for handling floating point numbers.
