npm install @stdlib/assert-is-odd

Usage

var isOdd = require( '@stdlib/assert-is-odd' );

isOdd( value )

Tests if a value is an odd number.

var Number = require( '@stdlib/number-ctor' );

var bool = isOdd( 5.0 );
// returns true

bool = isOdd( new Number( 5.0 ) );
// returns true

bool = isOdd( 6.0 );
// returns false

bool = isOdd( -3.14 );
// returns false

bool = isOdd( null );
// returns false

bool = isOdd( NaN );
// returns false

isOdd.isPrimitive( value )

Tests if a value is an odd primitive number.

var Number = require( '@stdlib/number-ctor' );

var bool = isOdd.isPrimitive( -5.0 );
// returns true

bool = isOdd.isPrimitive( new Number( -5.0 ) );
// returns false

isOdd.isObject( value )

Tests if a value is a Number object having an odd number value.

var Number = require( '@stdlib/number-ctor' );

var bool = isOdd.isObject( 5.0 );
// returns false

bool = isOdd.isObject( new Number( 5.0 ) );
// returns true

Examples

var Number = require( '@stdlib/number-ctor' );
var isOdd = require( '@stdlib/assert-is-odd' );

var bool = isOdd( 5.0 );

// returns true

bool = isOdd( 0.0 );
// returns false

bool = isOdd( 4.0 );
// returns false
