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!

isInteger

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

Test if a finite double-precision floating-point number is an integer.

Installation

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

Usage

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

isInteger( x )

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

1var bool = isInteger( 1.0 );
2// returns true

Notes

The function assumes a finite number. If provided positive or negative infinity, the function will return true, when, in fact, the result is undefined. If x can be infinite, wrap the implementation as follows:

1function check( x ) {
2    return (
3        x < Infinity &&
4        x > -Infinity &&
5        isInteger( x )
6    );
7}
8
9var bool = check( Infinity );
10// returns false
11
12bool = check( -Infinity );
13// returns false

Examples

1var isInteger = require( '@stdlib/math-base-assert-is-integer' );
2
3var bool = isInteger( -5.0 );
4// returns true
5
6bool = isInteger( 3.14 );
7// returns false
8
9bool = isInteger( NaN );
10// returns false

C APIs

Usage

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

stdlib_base_is_integer( x )

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

1bool out = stdlib_base_is_integer( 1.0 );
2// returns true
3
4out = stdlib_base_is_integer( 3.14 );
5// returns false

The function accepts the following arguments:

x: [in] double input value.

1bool stdlib_base_is_integer( const double x );

Examples

1#include "stdlib/math/base/assert/is_integer.h"
2#include <stdio.h>
3#include <stdlib.h>
4#include <stdbool.h>
5
6int main( void ) {
7    double x;
8    bool v;
9    int i;
10    
11    for ( i = 0; i < 100; i++ ) {
12        x = ( ( (double)rand() / (double)RAND_MAX ) * 100.0 ) - 50.0;
13        v = stdlib_base_is_integer( x );
14        printf( "x = %lf, is_integer(x) = %s\n", x, ( v ) ? "true" : "false" );
15    }
16}
