Test if a 32-bit integer is odd.
npm install @stdlib/math-base-assert-int32-is-oddWe 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!

> Test if a 32-bit integer is odd.
``bash`
npm install @stdlib/math-base-assert-int32-is-odd
`javascript`
var isOdd = require( '@stdlib/math-base-assert-int32-is-odd' );
#### isOdd( x )
Tests if 32-bit integer is odd.
`javascript
var bool = isOdd( 5 );
// returns true
bool = isOdd( -2 );
// returns false
bool = isOdd( 0 );
// returns false
`
`javascript
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';
}

`c`
#include "stdlib/math/base/assert/int32_is_odd.h"
#### stdlib_base_int32_is_odd( x )
Tests if a 32-bit integer is odd.
`c
#include
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.
`c`
bool stdlib_base_int32_is_odd( const int32_t x );
`c
#include "stdlib/math/base/assert/int32_is_odd.h"

b = stdlib_base_int32_is_odd( x[ i ] );
printf( "Value: %d. int32 Is Odd? %s.\n", x[ i ], ( b ) ? "True" : "False" );
