Description
The IsInteger
function returns true
only if value
is an
integer number, otherwise it returns
false
.
Parameters
Argument | Type | Definition and Requirements |
---|---|---|
|
Any |
Any value, which is to be tested to determine whether it is an integer number or not. |
Examples
The following query uses Map
to iterate
over an array of all of the types of values that can be tested by a
type-check function, passing each item into a
Lambda
function that returns an
object, which contains the value and the result of calling IsInteger
with that value:
