    The ToDecimal operator converts the value of its argument 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 the decimal value returned by this operator 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 null. If the input is Boolean, true will result in 1.0, false will result in 0.0. If the argument is null, the result is null.
