+ +## 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 +``` + +
