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!
isNonNegativeInteger
Test if a finite double-precision floating-point number is a nonnegative integer.
Installation
1npm install @stdlib/math-base-assert-is-nonnegative-integer
Usage
1var isNonNegativeInteger = require( '@stdlib/math-base-assert-is-nonnegative-integer' );
isNonNegativeInteger( x )
Tests if a finite double-precision floating-point number is a nonnegative integer.
1var bool = isNonNegativeInteger( 1.0 ); 2// returns true 3 4bool = isNonNegativeInteger( 0.0 ); 5// returns true 6 7bool = isNonNegativeInteger( -10.0 ); 8// returns false
Notes
-
The function assumes a finite
number. If provided positiveinfinity, the function will returntrue, when, in fact, the result is undefined. Ifxcan beinfinite, wrap the implementation as follows:1function check( x ) { 2 return ( 3 x < Infinity && 4 isNonNegativeInteger( x ) 5 ); 6} 7 8var bool = check( Infinity ); 9// returns false -
The function does not distinguish between positive and negative
zero.1var bool = isNonNegativeInteger( 0.0 ); 2// returns true 3 4bool = isNonNegativeInteger( -0.0 ); 5// returns true
Examples
1var isNonNegativeInteger = require( '@stdlib/math-base-assert-is-nonnegative-integer' ); 2 3var bool = isNonNegativeInteger( 5.0 ); 4// returns true 5 6bool = isNonNegativeInteger( 0.0 ); 7// returns true 8 9bool = isNonNegativeInteger( -1.0 ); 10// returns false 11 12bool = isNonNegativeInteger( 3.14 ); 13// returns false 14 15bool = isNonNegativeInteger( NaN ); 16// returns false
C APIs
Usage
1#include "stdlib/math/base/assert/is_nonnegative_integer.h"
stdlib_base_is_nonnegative_integer( x )
Tests if a finite double-precision floating-point number is a nonnegative integer.
1bool out = stdlib_base_is_nonnegative_integer( 1.0 ); 2// returns true 3 4out = stdlib_base_is_nonnegative_integer( -10.0 ); 5// returns false
The function accepts the following arguments:
- x:
[in] doubleinput value.
1bool stdlib_base_is_nonnegative_integer( const double x );
Examples
1#include "stdlib/math/base/assert/is_nonnegative_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_nonnegative_integer( x ); 14 printf( "x = %lf, is_nonnegative_integer(x) = %s\n", x, ( v ) ? "true" : "false" ); 15 } 16}
