Description | Use the is not strictly operator to determine what the true type of
a value is not. The true type of a value is the representation which
the engine is currently holding for it, without performing any
implicit type coercion. The true type of a value can be one of the
following:
- nothing:
no value, typically seen as empty
- boolean:
either true or false, typically seen as the result of a
comparison operator
- integer:
a number with no fractional part
- real:
a number with a fractional part
- string:
a piece of text (sequence of characters)
- binary string: a sequence of bytes
- array:
an associative array
The is not strictly operator differs from is not a in that it does
not perform any type coercion. For example, x not is an integer
would return false only when x is neither an integer nor a string
which parses as an integer; whereas x is not strictly an integer
only returns false if x is not currently an integer.
