The ConvertsToLong operator returns true if the value of its argument is or can be converted to a Long value. The operator accepts strings using the following format: (+|-)?#0 Meaning an optional polarity indicator, followed by any number of digits (including none), followed by at least one digit. See the Formatting Strings topic in the CQL Reference (Appendix B) of the CQL Specification for a description of formatting strings. Note that for this operator to return true, the input must be a valid value in the range representable for Long values in CQL. If the input string is not formatted correctly, or cannot be interpreted as a valid Long value, the result is false. If the input is a Boolean, the result is true. If the argument is null, the result is null.
