Package Exports
- @stdlib/complex-imagf
- @stdlib/complex-imagf/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/complex-imagf) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
imagf
Return the imaginary component of a single-precision complex floating-point number.
Installation
npm install @stdlib/complex-imagfUsage
var imagf = require( '@stdlib/complex-imagf' );imagf( z )
Returns the imaginary component of a single-precision complex floating-point number.
var Complex64 = require( '@stdlib/complex-float32' );
var z = new Complex64( 5.0, 3.0 );
var im = imagf( z );
// returns 3.0Examples

Usage
#include "stdlib/complex/imagf.h"stdlib_imagf( z )
Returns the imaginary component of a single-precision complex floating-point number.
