Evaluate the identity function for an unsigned 8-bit integer.

Package Exports

  • @stdlib/number-uint8-base-identity
  • @stdlib/number-uint8-base-identity/dist

  • @stdlib/number-uint8-base-identity/lib/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/number-uint8-base-identity) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

About stdlib...

We 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!

Identity Function

NPM version Build Status Coverage Status

Evaluate the identity function of an unsigned 8-bit integer.

The identity-function is defined as

Identity function

for all x.

Installation

npm install @stdlib/number-uint8-base-identity

Usage

var identity = require( '@stdlib/number-uint8-base-identity' );

identity( x )

Evaluates the identity function for an unsigned 8-bit integer.

var v = identity( 1 );
// returns 1

v = identity( 2 );
// returns 2

v = identity( 0 );
// returns 0

v = identity( 255 );
// returns 255

Examples

var discreteUniform = require( '@stdlib/random-array-discrete-uniform' );
var logEachMap = require( '@stdlib/console-log-each-map' );
var identity = require( '@stdlib/number-uint8-base-identity' );

var opts = {
    'dtype': 'uint8'
};

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

// Perform element-wise operation:
logEachMap( 'identity(%d) = %d', x, identity );

C APIs

Usage

#include "stdlib/number/uint8/base/identity.h"

stdlib_base_uint8_identity( x )

Evaluates the identity function for an unsigned 8-bit integer.

#include <stdint.h>

uint8_t y = stdlib_base_uint8_identity( 2 );
// returns 2

The function accepts the following arguments:

  • x: [in] uint8_t input value.
uint8_t stdlib_base_uint8_identity( const uint8_t x );

Examples

#include "stdlib/number/uint8/base/identity.h"
#include <stdint.h>
#include <stdio.h>

int main( void ) {
    const uint8_t x[] = { 3, 5, 10, 12 };

    uint8_t y;
    int i;
    for ( i = 0; i < 4; i++ ) {
        y = stdlib_base_uint8_identity( x[ i ] );
        printf( "f(%u) = %u\n", x[ i ], y );
    }
}

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
