+# isOddf

+
+## Usage
+
+```javascript
+var isOddf = require( '@stdlib/math/base/assert/is-oddf' );
+```
+
+#### isOddf( x )
+
+Tests if a **finite** single-precision floating-point numeric value is an odd number.
+
+```javascript
+var bool = isOddf( 5.0 );
+// returns true
+
+bool = isOddf( -2.0 );
+// returns false
+
+bool = isOddf( 0.0 );
+// returns false
+
+bool = isOddf( NaN );
+// returns false
+```

+
+## Notes
+
+-   The function assumes a **finite** `number`. If provided positive or negative `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 &&
+            x > -Infinity &&
+            isOddf( x )
+        );
+    }
+
+    var bool = check( Infinity );
+    // returns false
+
+    bool = check( -Infinity );
+    // returns false
+    ```

+### Usage
+
+```c
+#include "stdlib/math/base/assert/is_oddf.h"
+```
+
+#### stdlib_base_is_oddf( x )
+
+Tests if a finite single-precision floating-point numeric value is an odd number.
+
+```c
+#include <stdbool.h>
+
+bool out = stdlib_base_is_oddf( 1.0f );
+// returns true
+
+out = stdlib_base_is_oddf( 4.0f );
+// returns false

+
+The function accepts the following arguments:
+
+-   **x**: `[in] float` input value.
+
+```c
+bool stdlib_base_is_oddf( const float x );
