Evaluate the identity function for a single-precision complex floating-point number.
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!
Evaluate the identity function of a single-precision complex floating-point number.
The identity-function is defined as
for all z.
npm install @stdlib/math-base-special-cidentityf
var cidentityf = require( '@stdlib/math-base-special-cidentityf' );
Evaluates the identity function for a single-precision complex floating-point number.
var Complex64 = require( '@stdlib/complex-float32' );
var real = require( '@stdlib/complex-real' );
var imag = require( '@stdlib/complex-imag' );
var v = cidentityf( new Complex64( -1.0, 2.0 ) );
// returns <Complex64>
var re = real( v );
// returns -1.0
var im = imag( v );
// returns 2.0
var discreteUniform = require( '@stdlib/random-base-discrete-uniform' );
var Complex64 = require( '@stdlib/complex-float32' );
var cidentityf = require( '@stdlib/math-base-special-cidentityf' );
var z;
var i;
for ( i = 0; i < 100; i++ ) {
z = new Complex64( discreteUniform( -50, 50 ), discreteUniform( -50, 50 ) );
console.log( 'identity(%s) = %s', z, cidentityf( z ) );
}
#include "stdlib/math/base/special/cidentityf.h"
Evaluates the identity function for a single-precision complex floating-point number.
#include <complex.h>
float complex y = stdlib_base_cidentityf( 2.0f+2.0f*I );
// returns 2.0f+2.0f*I
The function accepts the following arguments:
[in] float complex input value.float complex stdlib_base_cidentityf( const float complex z );
#include "stdlib/math/base/special/cidentityf.h"
#include <stdio.h>
#include <complex.h>
int main( void ) {
const float complex x[] = { 3.14f+1.0f*I, -3.14f-1.0f*I, 0.0f+0.0f*I, 0.0f/0.0f+0.0f/0.0f*I };
float complex v;
float complex y;
int i;
for ( i = 0; i < 4; i++ ) {
v = x[ i ];
y = stdlib_base_cidentityf( v );
printf( "f(%f + %f) = %f + %f\n", crealf( v ), cimagf( v ), crealf( y ), cimagf( y ) );
}
}
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.
