isComposite

Test if a number is a composite.

A composite number is defined as a positive integer value greater than 1 which has at least one divisor other than 1 and itself (i.e., an integer value which can be formed by multiplying two smaller positive integers).

Usage

var isComposite = require( '@stdlib/math/base/assert/is-composite' );

isComposite( x )

Tests if a number is a composite.

var bool = isComposite( 4.0 );
// returns true

Examples

var isComposite = require( '@stdlib/math/base/assert/is-composite' );

var bool = isComposite( 4.0 );
// returns true

bool = isComposite( 7.0 );
// returns false

bool = isComposite( NaN );
// returns false
