isPrime

Test if a value is a prime number.

A prime number is defined as an integer value greater than 1 which is only divisible by 1 and itself.

Usage

var isPrime = require( '@stdlib/assert/is-prime' );

isPrime( value )

Tests if a value is a prime number.

var Number = require( '@stdlib/number/ctor' ); var bool = isPrime( 5.0 ); // returns true bool = isPrime( new Number( 5.0 ) ); // returns true bool = isPrime( 3.14 ); // returns false bool = isPrime( -5.0 ); // returns false bool = isPrime( NaN ); // returns false bool = isPrime( null ); // returns false

isPrime.isPrimitive( value )

Tests if a value is a primitive prime number.

var Number = require( '@stdlib/number/ctor' ); var bool = isPrime.isPrimitive( 5.0 ); // returns true bool = isPrime.isPrimitive( new Number( 5.0 ) ); // returns false

isPrime.isObject( value )

Tests if a value is a Number object having a value which is a prime number.

var Number = require( '@stdlib/number/ctor' ); var bool = isPrime.isObject( 5.0 ); // returns false bool = isPrime.isObject( new Number( 5.0 ) ); // returns true

Examples

var Number = require( '@stdlib/number/ctor' ); var isPrime = require( '@stdlib/assert/is-prime' ); var bool = isPrime( 5.0 ); // returns true bool = isPrime( new Number( 5.0 ) ); // returns true bool = isPrime( 11.0 ); // returns true bool = isPrime( 2.0 ); // returns true bool = isPrime( 3.14 ); // returns false bool = isPrime( -5.0 ); // returns false bool = isPrime( NaN ); // returns false bool = isPrime( '0.5' ); // returns false bool = isPrime( null ); // returns false
