+## Usage

+#### isNonNegativeIntegerf( x )
+
+Tests if a finite [single-precision floating-point number][ieee754] is a nonnegative `integer`.

+```javascript
+var bool = isNonNegativeIntegerf( 1.0 );
+// returns true
+

+
+## Notes
+
+-   The function assumes a **finite** `number`. If provided positive `infinity`, the function will return `true`, when, in fact, the result is undefined. If `x` can be `infinite`, wrap the implementation as follows:
+
+    ```javascript
+    function check( x ) {
+        return (
+            x < Infinity &&
+            isNonNegativeIntegerf( x )
+        );
+    }
+
+    var bool = check( Infinity );
+    // returns false
+    ```
+
+-   The function does **not** distinguish between positive and negative `zero`.
+
+    ```javascript
+    var bool = isNonNegativeIntegerf( 0.0 );
+    // returns true
+
+    bool = isNonNegativeIntegerf( -0.0 );
+    // returns true
+    ```
