function asecf( x ) {
	return acosf( float64ToFloat32( 1.0 / float64ToFloat32( x ) ) );
}
Computes the inverse (arc) secant of a single-precision floating-point number.

## Method

```text
\operatorname{asecf}(x) = \operatorname{acosf}(\frac{1}{x})
```

@param {number} x - input value
@returns {number} inverse (arc) secant

@example
var v = asecf( 1.0 );
// returns 0.0

@example
var v = asecf( 2.0 );
// returns ~1.0472

@example
var v = asecf( NaN );
// returns NaN
