About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

isPrime

$NPM version$ $Build Status$ $Coverage Status$

Test if a number is a prime.

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

Installation

1npm install @stdlib/math-base-assert-is-prime

Usage

1var isPrime = require( '@stdlib/math-base-assert-is-prime' );

isPrime( x )

Tests if a number is a prime.

1var bool = isPrime( 7.0 );
2// returns true

Examples

1var isPrime = require( '@stdlib/math-base-assert-is-prime' );
2
3var bool = isPrime( 11.0 );
4// returns true
5
6bool = isPrime( 3.14 );
7// returns false
8
9bool = isPrime( NaN );
10// returns false

C APIs

Usage

1#include "stdlib/math/base/assert/is_prime.h"

stdlib_base_is_prime( x )

Tests if a finite double-precision floating-point number is a prime number.

1#include <stdbool.h>
2
3bool out = stdlib_base_is_prime( 11.0 );
4// returns true
5
6out = stdlib_base_is_prime( 3.14 );
7// returns false

The function accepts the following arguments:

x: [in] double input value.

1bool stdlib_base_is_prime( const double x );

Examples

1#include "stdlib/math/base/assert/is_prime.h"
2#include <stdio.h>
3#include <stdbool.h>
4
5int main( void ) {
6    const double x[] = { 5.0, -5.0, 3.14, -3.14, -2.0, 2.0, 0.0, 0.0/0.0 };
7
8    bool b;
9    int i;
10    for ( i = 0; i < 6; i++ ) {
11        b = stdlib_base_is_prime( x[ i ] );
12        printf( "Value: %lf. Is Prime? %s.\n", x[ i ], ( b ) ? "True" : "False" );
13    }
14}
