Compute the hypotenuse avoiding overflow and underflow (single-precision).
npm install @stdlib/math-base-special-hypotfWe believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js. The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases. When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there. To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

> Compute the [hypotenuse][hypotenuse] avoiding overflow and underflow (single-precision).
``bash`
npm install @stdlib/math-base-special-hypotf
`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 and the other argument is not +-Infinity, the function returns NaN.
`javascript
var h = hypotf( NaN, 12.0 );
// returns NaN
h = hypotf( 5.0, NaN );
// returns NaN
`
`javascript
var discreteUniform = require( '@stdlib/random-array-discrete-uniform' );
var logEachMap = require( '@stdlib/console-log-each-map' );
var hypotf = require( '@stdlib/math-base-special-hypotf' );
var opts = {
'dtype': 'float32'
};
var x = discreteUniform( 100, -50, 50, opts );
var y = discreteUniform( 100, -50, 50, opts );
logEachMap( 'h(%d,%d) = %0.4f', x, y, hypotf );

#### 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.[in] float
- y: input value.
`c`
float stdlib_base_hypotf( const float x, const float y );
`c
#include "stdlib/math/base/special/hypotf.h"

const float x[] = { 3.0f, 4.0f, 5.0f, 12.0f };
float y;

for ( i = 0; i < 4; i += 2 ) {
y = stdlib_base_hypotf( x[ i ], x[ i+1 ] );
printf( "hypot(%f, %f) = %f\n", x[ i ], x[ i+1 ], y );
}
