npm install @stdlib/number-int8-base-identityWe 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][npm-image]][npm-url] [![Build Status][test-image]][test-url] [![Coverage Status][coverage-image]][coverage-url]
> Evaluate the [identity function][identity-function] of a signed 8-bit integer.
The [identity-function][identity-function] is defined as
for all x.
Installation
``bash`
npm install @stdlib/number-int8-base-identity
Usage
`javascript`
var identity = require( '@stdlib/number-int8-base-identity' );
#### identity( x )
Evaluates the [identity function][identity-function] for a signed 8-bit integer.
`javascript
var v = identity( 1 );
// returns 1
v = identity( 2 );
// returns 2
v = identity( 0 );
// returns 0
v = identity( 127 );
// returns 127
`
Examples
`javascript
var discreteUniform = require( '@stdlib/random-array-discrete-uniform' );
var logEachMap = require( '@stdlib/console-log-each-map' );
var identity = require( '@stdlib/number-int8-base-identity' );
var opts = {
'dtype': 'int8'
};
// 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
$3
`c`
#include "stdlib/number/int8/base/identity.h"
#### stdlib_base_int8_identity( x )
Evaluates the identity function for a signed 8-bit integer.
`c
#include
int8_t y = stdlib_base_int8_identity( 2 );
// returns 2
`
The function accepts the following arguments:
- x: [in] int8_t input value.
`c`
int8_t stdlib_base_int8_identity( const int8_t x );

int main( void ) {
const int8_t x[] = { 3, 5, 10, 12 };
int8_t y;
int i;
for ( i = 0; i < 4; i++ ) {
y = stdlib_base_int8_identity( x[ i ] );
printf( "f(%d) = %d\n", x[ i ], y );
}
}
