# reimf
[![NPM version][npm-image]][npm-url] [![Build Status][test-image]][test-url] [![Coverage Status][coverage-image]][coverage-url]
> Return the real and imaginary components of a single-precision complex floating-point number.
## Installation
```bash
npm install @stdlib/complex-reimf
```
## Usage
```javascript
var reimf = require( '@stdlib/complex-reimf' );
```
#### reimf( z )
Returns the **real** and **imaginary** components of a single-precision complex floating-point number.
```javascript
var Complex64 = require( '@stdlib/complex-float32' );
var z = new Complex64( 5.0, 3.0 );
var out = reimf( z );
// returns [ 5.0, 3.0 ]
```
## Examples
```javascript
var Complex64 = require( '@stdlib/complex-float32' );
var randu = require( '@stdlib/random-base-randu' );
var round = require( '@stdlib/math-base-special-round' );
var reimf = require( '@stdlib/complex-reimf' );
var out;
var re;
var im;
var z;
var i;
for ( i = 0; i < 100; i++ ) {
re = round( (randu()*100.0) - 50.0 );
im = round( (randu()*50.0) - 25.0 );
z = new Complex64( re, im );
out = reimf( z );
console.log( '%s => %d, %d', z.toString(), out[ 0 ], out[ 1 ] );
}
```

## C APIs
### Usage
```c
#include "stdlib/complex/reimf.h"
```
#### stdlib_reimf( z, \*re, \*im )
Returns the real and imaginary components of a single-precision complex floating-point number.
```c
#include "stdlib/complex/float32.h"
stdlib_complex64_t z = stdlib_complex64( 5.0f, 2.0f );
// ...
float re;
float im;
stdlib_reimf( z, &re, &im );
```
The function accepts the following arguments:
- **z**: `[in] stdlib_complex64_t` single-precision complex floating-point number.
- **re**: `[out] float*` destination for real component.
- **im**: `[out] float*` destination for imaginary component.
```c
void stdlib_reimf( const stdlib_complex64_t z, float *re, float *im );
```
### Examples
```c
#include "stdlib/complex/reimf.h"
#include "stdlib/complex/float32.h"
#include
int main() {
stdlib_complex64_t x[] = {
stdlib_complex64( 5.0f, 2.0f ),
stdlib_complex64( -2.0f, 1.0f ),
stdlib_complex64( 0.0f, -0.0f ),
stdlib_complex64( 0.0f/0.0f, 0.0f/0.0f )
};
float re;
float im;
int i;
for ( i = 0; i < 4; i++ ) {
stdlib_reimf( x[ i ], &re, &im );
printf( "reimf(v) = %f, %f\n", re, im );
}
}
```
