---|
value | | The expression which will be tested for its type.

1 + 200 is strictly an integer
(100 is 100) is strictly a boolean

Description | Use the is strictly operator to determine the true type of a
value. 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 strictly operator differs from is a in that it does not
perform any type coercion. For example, x is an integer would return
true if x is truly an integer or if it is a string which can be parsed
as an integer; whereas x is strictly an integer only returns true if
x is currently an integer (and not a string).
