Handling of literals and values

This section discusses how characters, numeric values, and NULL values are used in EQL.

• Character handling
  EQL accepts all Unicode characters.
• Handling of upper- and lower-case
  This topic discusses character case handling in EQL.
• 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.
• 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 754 2008 standard for handling floating point numbers.
• Integer type promotion
  In some cases, EQL supports automatic value promotion of integers to doubles when there is no risk of loss of information.
• Handling of precision for doubles
  This topic provides information on the limits of precision in serialization of doubles in EQL results.
