sub

Subtract two unsigned 16-bit integers.

Installation

npm install @stdlib/number-uint16-base-sub

Usage

var sub = require( '@stdlib/number-uint16-base-sub' );

sub( x, y )

Subtracts two unsigned 16-bit integers.

var v = sub( 5, 1 );
// returns 4

v = sub( 5, 2 );
// returns 3

v = sub( 5, 0 );
// returns 5

Notes

• The function performs C-like subtraction of two unsigned 16-bit integers, including wraparound semantics.

Examples

var discreteUniform = require( '@stdlib/random-array-discrete-uniform' );
var logEachMap = require( '@stdlib/console-log-each-map' );
var sub = require( '@stdlib/number-uint16-base-sub' );

var opts = {
    'dtype': 'uint16'
};

// Create arrays of random values:
var x = discreteUniform( 100, 0, 50, opts );
var y = discreteUniform( 100, 0, 50, opts );

// Perform element-wise subtraction:
logEachMap( '%d - %d = %d', x, y, sub );

C APIs

Usage

#include "stdlib/number/uint16/base/sub.h"

stdlib_base_uint16_sub( x, y )

Subtracts two unsigned 16-bit integers.

#include <stdint.h>

uint16_t v = stdlib_base_uint16_sub( 5, 2 );
// returns 3

The function accepts the following arguments:

• x: [in] uint16_t first input value.
• y: [in] uint16_t second input value.

uint16_t stdlib_base_uint16_sub( const uint16_t x, const uint16_t y );

Examples

#include "stdlib/number/uint16/base/sub.h"
#include <stdint.h>
#include <stdio.h>

int main( void ) {
    const uint16_t x[] = { 3, 5, 10, 12 };
    const uint16_t y[] = { 6, 2, 11, 24 };

    uint16_t z;
    int i;
    for ( i = 0; i < 4; i++ ) {
        z = stdlib_base_uint16_sub( x[ i ], y[ i ] );
        printf( "%d - %d = %d\n", x[ i ], y[ i ], z );
    }
}
