isOdd

Test if a 32-bit integer is odd.

Usage

var isOdd = require( '@stdlib/math/base/assert/int32-is-odd' );

isOdd( x )

Tests if 32-bit integer is odd.

var bool = isOdd( 5 );
// returns true

bool = isOdd( -2 );
// returns false

bool = isOdd( 0 );
// returns false

Examples

var discreteUniform = require( '@stdlib/random/array/discrete-uniform' );
var logEachMap = require( '@stdlib/console/log-each-map' );
var isOdd = require( '@stdlib/math/base/assert/int32-is-odd' );

var opts = {
    'dtype': 'int32'
};
var x = discreteUniform( 100, 0, 100, opts );

function isOddWrapper( integer ) {
    return ( isOdd( integer ) ) ? 'odd' : 'not odd';
}
logEachMap( '%d is %s', x, isOddWrapper );

C APIs

Usage

#include "stdlib/math/base/assert/int32_is_odd.h"

stdlib_base_int32_is_odd( x )

Tests if a 32-bit integer is odd.

#include <stdbool.h>

bool out = stdlib_base_int32_is_odd( 5 );
// returns true

out = stdlib_base_int32_is_odd( -2 );
// returns false

The function accepts the following arguments:

• x: [in] int32_t input value.

bool stdlib_base_int32_is_odd( const int32_t x );

Examples

#include "stdlib/math/base/assert/int32_is_odd.h"
#include <stdio.h>
#include <stdbool.h>
#include <stdint.h>

int main( void ) {
    const int32_t x[] = { 5, -5, 3, -3, 0, 2 };

    bool b;
    int i;
    for ( i = 0; i < 5; i++ ) {
        b = stdlib_base_int32_is_odd( x[ i ] );
        printf( "Value: %d. int32 Is Odd? %s.\n", x[ i ], ( b ) ? "True" : "False" );
    }
}
