Multiply two unsigned 32-bit integers.
npm install @stdlib/number-uint32-base-mulWe 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!

> Multiply two unsigned 32-bit integers.
``bash`
npm install @stdlib/number-uint32-base-mul
`javascript`
var mul = require( '@stdlib/number-uint32-base-mul' );
#### mul( x, y )
Multiplies two unsigned 32-bit integers.
`javascript
var v = mul( 10>>>0, 4>>>0 );
// returns 40
v = mul( 2147483648>>>0, 5>>>0 ); // 2^31 * 5 = 10737418240 => 32-bit integer overflow
// returns 2147483648
`
- The function performs C-like multiplication of two unsigned 32-bit integers, including wraparound semantics.
`javascript
var discreteUniform = require( '@stdlib/random-array-discrete-uniform' );
var logEachMap = require( '@stdlib/console-log-each-map' );
var mul = require( '@stdlib/number-uint32-base-mul' );
var opts = {
'dtype': 'uint32'
};
// Create arrays of random values:
var x = discreteUniform( 100, 0, 50, opts );
var y = discreteUniform( 100, 0, 50, opts );
// Perform element-wise multiplication:
logEachMap( '%d * %d = %d', x, y, mul );

#### stdlib_base_uint32_mul( x, y )
Multiplies two unsigned 32-bit integers.
`c
#include
uint32_t v = stdlib_base_uint32_mul( 5, 2 );
// returns 10
`
The function accepts the following arguments:
- x: [in] uint32_t first input value.[in] uint32_t
- y: second input value.
`c`
uint32_t stdlib_base_uint32_mul( const uint32_t x, const uint32_t y );
`c
#include "stdlib/number/uint32/base/mul.h"
#include
#include
int main( void ) {
const uint32_t x[] = { 3, 5, 10, 12 };
const uint32_t y[] = { 6, 2, 11, 24 };
uint32_t z;
int i;
for ( i = 0; i < 4; i++ ) {
z = stdlib_base_uint32_mul( x[ i ], y[ i ] );
printf( "%u * %u = %u\n", x[ i ], y[ i ], z );
}
