isNonNegativeFinite
Test if a numeric value is a nonnegative finite number.
Installation
npm install @stdlib/math-base-assert-is-nonnegative-finite
Usage
var isNonNegativeFinite = require( '@stdlib/math-base-assert-is-nonnegative-finite' );
isNonNegativeFinite( x )
Tests if a numeric
value is a nonnegative finite number.
var bool = isNonNegativeFinite( 3.14 );
// returns true
bool = isNonNegativeFinite( -2.0 );
// returns false
Examples
var isNonNegativeFinite = require( '@stdlib/math-base-assert-is-nonnegative-finite' );
var bool = isNonNegativeFinite( 5.0 );
// returns true
bool = isNonNegativeFinite( 3.14 );
// returns true
bool = isNonNegativeFinite( 0.0 );
// returns true
bool = isNonNegativeFinite( -2.0 );
// returns false
bool = isNonNegativeFinite( Infinity );
// returns false
bool = isNonNegativeFinite( NaN );
// returns false
C APIs
Usage
#include "stdlib/math/base/assert/is_nonnegative_finite.h"
stdlib_base_is_nonnegative_finite( x )
Tests if a numeric value is a nonnegative finite number.
#include <stdbool.h>
bool out = stdlib_base_is_nonnegative_finite( 3.14 );
// returns true
out = stdlib_base_is_nonnegative_finite( -2.0 );
// returns false
The function accepts the following arguments:
- x:
[in] double
input value.
bool stdlib_base_is_nonnegative_finite( const double x );
Examples
#include "stdlib/math/base/assert/is_nonnegative_finite.h"
#include <stdio.h>
#include <stdbool.h>
int main( void ) {
const double x[] = { 5.0, -5.0, 3.14, -3.14, 0.0, 0.0/0.0 };
bool b;
int i;
for ( i = 0; i < 6; i++ ) {
b = stdlib_base_is_nonnegative_finite( x[ i ] );
printf( "Value: %lf. Is nonnegative finite? %s.\n", x[ i ], ( b ) ? "True" : "False" );
}
}
