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!

castReturn

Wrap a function and cast a function's return value to a complex number.

## Installation ```bash npm install @stdlib/complex-base-cast-return ``` Alternatively, - To load the package in a website via a `script` tag without installation and bundlers, use the [ES Module][es-module] available on the [`esm`][esm-url] branch (see [README][esm-readme]). - If you are using Deno, visit the [`deno`][deno-url] branch (see [README][deno-readme] for usage intructions). - For use in Observable, or in browser/node environments, use the [Universal Module Definition (UMD)][umd] build available on the [`umd`][umd-url] branch (see [README][umd-readme]). The [branches.md][branches-url] file summarizes the available branches and displays a diagram illustrating their relationships. To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.

## Usage ```javascript var castReturn = require( '@stdlib/complex-base-cast-return' ); ``` #### castReturn( fcn, nargs, ctor ) Returns a function which wraps a function and casts a function's return value to a complex number. ```javascript var Complex64 = require( '@stdlib/complex-float32-ctor' ); var addf = require( '@stdlib/number-float32-base-add' ); var f = castReturn( addf, 2, Complex64 ); // returns ``` The function accepts the following arguments: - **fcn**: the function to wrap. - **nargs**: the number of arguments to be provided to the wrapped function. - **ctor**: complex number constructor for converting real numbers to complex numbers.

## Notes - The returned function **assumes** that the wrapped function returns either a real or complex number. - The returned function **assumes** that, if a return value is non-numeric (i.e., not of type `number`), then the return value is a complex number. The returned function does **not** verify that non-numeric return values are, in fact, complex number objects. The returned function returns non-numeric return values from the wrapped function without modification.

## Examples ```javascript var Complex64 = require( '@stdlib/complex-float32-ctor' ); var addf = require( '@stdlib/number-float32-base-add' ); var realf = require( '@stdlib/complex-float32-real' ); var imagf = require( '@stdlib/complex-float32-imag' ); var castReturn = require( '@stdlib/complex-base-cast-return' ); var f = castReturn( addf, 2, Complex64 ); // ... var z = f( 3.0, 4.0 ); // returns var re = realf( z ); // returns 7.0 var im = imagf( z ); // returns 0.0 console.log( '%d + %di', re, im ); // => '7 + 0i' ```

The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
