## Usage
38+
39+
```javascript
40+
var minmaxabsf = require( '@stdlib/math/base/special/minmaxabsf' );
41+
```
42+
43+
#### minmaxabsf( x, y )
44+
45+
Returns the minimum and maximum absolute values of two single-precision floating-point numbers in a single pass.
46+
47+
```javascript
48+
var v = minmaxabsf( 4.2, 3.14 );
49+
// returns [ 3.14, 4.2 ]
50+
51+
v = minmaxabsf( +0.0, -0.0 );
52+
// returns [ 0.0, 0.0 ]
53+
```
54+
55+
If any argument is `NaN`, the function returns `NaN` for both the minimum value and the maximum value.
56+
57+
```javascript
58+
var v = minmaxabsf( 4.2, NaN );
59+
// returns [ NaN, NaN ]
60+
61+
v = minmaxabsf( NaN, 3.14 );
62+
// returns [ NaN, NaN ]
63+
```
64+
65+
#### minmaxabsf.assign( x, y, out, stride, offset )
66+
67+
Returns the minimum and maximum absolute values of two single-precision floating-point numbers in a single pass and assigns results to a provided output array.
68+
69+
```javascript
70+
var Float32Array = require( '@stdlib/array/float32' );
71+
72+
var out = new Float32Array( 2 );
73+
74+
var v = minmaxabsf.assign( 5.0, -2.0, out, 1, 0 );
75+
// returns <Float32Array>[ 2.0, 5.0 ]
76+
77+
var bool = ( v === out );
78+
// returns true
79+
```

### Usage
140+
141+
```c
142+
#include "stdlib/math/base/special/minmaxabsf.h"
143+
```
144+
145+
#### stdlib_base_minmaxabsf( x, y, &min, &max )
146+
147+
Evaluates the minimum and maximum absolute values of two single-precision floating-point numbers in a single pass.
148+
149+
```c
150+
float x = -3.14f;
151+
float y = 2.71f;
152+
153+
float min;
154+
float max;
155+
stdlib_base_minmaxabsf( x, y, &min, &max );
156+
```
157+
158+
The function accepts the following arguments:
159+
160+
- **x**: `[in] float` first number.
161+
- **y**: `[in] float` second number.
162+
- **min**: `[out] float` destination for the minimum absolute value.
163+
- **max**: `[out] float` destination for the maximum absolute value.
164+
165+
```c
166+
void stdlib_base_minmaxabsf( const float x, const float y, float* min, float* max );
167+
```
