function acscf( x ) {
	return asinf( float64ToFloat32( 1.0 / float64ToFloat32( x ) ) );
}
Computes the arccosecant of a single-precision floating-point number.

## Method

```text
\operatorname{acscf}(x) = \operatorname{asinf}(\frac{1}{x})
```

@param {number} x - input value
@returns {number} arccosecant (in radians)

@example
var v = acscf( 1.0 );
// returns ~1.57

@example
var v = acscf( 3.141592653589793 );
// returns ~0.32

@example
var v = acscf( -3.141592653589793 );
// returns ~-0.32

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