-/**
-Get the expression_result as a bool\n
-The boolean function converts its argument to a boolean as follows:
-- a number is true if and only if it is neither positive or negative zero nor NaN
-- a node-set is true if and only if it is non-empty
-- a string is true if and only if its length is non-zero
-- an object of a type other than the four basic types is converted to a boolean in a way that is dependent on that type
