The ConvertsToDecimal operator returns true if the value of its argument is or can be converted to a Decimal value. The operator accepts strings using the following format: (+|-)?#0(.0#)? Meaning an optional polarity indicator, followed by any number of digits (including none), followed by at least one digit, followed optionally by a decimal point, at least one digit, and any number of additional digits (including none). 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 value must be limited in precision and scale to the maximum precision and scale representable for Decimal values within CQL. If the input string is not formatted correctly, or cannot be interpreted as a valid Decimal value, the result is false. If the input is a Boolean, the result is true. If the argument is null, the result is null.
