## Usage

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

#### hypotf( x, y )

Computes the [hypotenuse][hypotenuse] avoiding overflow and underflow (single-precision).

```javascript
var h = hypotf( -5.0, 12.0 );
// returns 13.0

h = hypotf( -0.0, -0.0 );
// returns +0.0
```

If either argument is `NaN`, the function returns `NaN`.

```javascript
var h = hypotf( NaN, 12.0 );
// returns NaN

h = hypotf( 5.0, NaN );
// returns NaN
```

### Usage

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

#### stdlib_base_hypotf( x, y )

Computes the hypotenuse avoiding overflow and underflow (single-precision).

```c
float h = stdlib_base_hypotf( 5.0f, 12.0f );
// returns 13.0f
```

The function accepts the following arguments:

-   **x**: `[in] float` input value.
-   **y**: `[in] float` input value.

```c
float stdlib_base_hypotf( const float x, const float y );
```
