## Usage

```javascript
var minmaxf = require( '@stdlib/math/base/special/minmaxf' );
```

#### minmaxf( x, y )

Returns the minimum and maximum of two single-precision floating-point numbers in a single pass.

```javascript
var v = minmaxf( 4.2, 3.14 );
// returns [ 3.14, 4.2 ]

v = minmaxf( +0.0, -0.0 );
// returns [ -0.0, +0.0 ]
```

If any argument is `NaN`, the function returns `NaN` for both the minimum value and the maximum value.

```javascript
var v = minmaxf( 4.2, NaN );
// returns [ NaN, NaN ]

v = minmaxf( NaN, 3.14 );
// returns [ NaN, NaN ]
```

#### minmaxf.assign( x, y, out, stride, offset )

Returns the minimum and maximum of two single-precision floating-point numbers in a single pass and assigns results to a provided output array.

```javascript
var Float32Array = require( '@stdlib/array/float32' );

var out = new Float32Array( 2 );

var v = minmaxf.assign( 5.0, -2.0, out, 1, 0 );
// returns <Float32Array>[ -2.0, 5.0 ]

var bool = ( v === out );
// returns true
```

### Usage

```c
#include "stdlib/math/base/special/minmaxf.h"
```

#### stdlib_base_minmaxf( x, y, &min, &max )

Evaluates the minimum and maximum of two single-precision floating-point numbers in a single pass.

```c
float x = 3.14f;
float y = 2.71f;

float min;
float max;
stdlib_base_minmaxf( x, y, &min, &max );
```

The function accepts the following arguments:

-   **x**: `[in] float` first number.
-   **y**: `[in] float` second number.
-   **min**: `[out] float` destination for the minimum value.
-   **max**: `[out] float` destination for the maximum value.

```c
void stdlib_base_minmaxf( const float x, const float y, float* min, float* max );
```

        printf( "x: %f, y: %f => min: %f, max: %f\n", x[ i ], y[ i ], min, max );
    }
