+# acschf
+
+> Compute the [hyperbolic arccosecant][inverse-hyperbolic-functions] of a single-precision floating-point number.
+
+
+
+## Usage
+
+```javascript
+var acschf = require( '@stdlib/math/base/special/acschf' );
+```
+
+#### acschf( x )
+
+Computes the [hyperbolic arccosecant][inverse-hyperbolic-functions] of `x`.
+
+```javascript
+var v = acschf( 0.0 );
+// returns Infinity
+
+v = acschf( -0.0 );
+// returns -Infinity
+
+v = acschf( 1.0 );
+// returns ~0.881
+
+v = acschf( -1.0 );
+// returns ~-0.881
+
+v = acschf( NaN );
+// returns NaN
+
+v = acschf( -Infinity );
+// returns -0.0
+
+v = acschf( Infinity );
+// returns 0.0
+```
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var uniform = require( '@stdlib/random/array/uniform' );
+var logEachMap = require( '@stdlib/console/log-each-map' );
+var acschf = require( '@stdlib/math/base/special/acschf' );
+
+var x = uniform( 100, 1.0, 5.0, {
+ 'dtype': 'float32'
+});
+
+logEachMap( 'acschf(%0.4f) = %0.4f', x, acschf );
+```

+
+
+
+## C APIs
+
+
+
+
+
+
+
+
+
+
+
+### Usage
+
+```c
+#include "stdlib/math/base/special/acschf.h"
+```
+
+#### stdlib_base_acschf( x )
+
+Computes the [hyperbolic arccosecant][inverse-hyperbolic-functions] of a single-precision floating-point number.
+
+```c
+float out = stdlib_base_acschf( 1.0f );
+// returns ~0.881f
+```
+
+The function accepts the following arguments:
+
+- **x**: `[in] float` input value.
+
+```c
+float stdlib_base_acschf( const float x );
+```
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+### Examples
+
+```c
+#include "stdlib/math/base/special/acschf.h"
+#include
+
+int main( void ) {
+ const float x[] = { -5.0f, -3.89f, -2.78f, -1.67f, -0.55f, 0.55f, 1.67f, 2.78f, 3.89f, 5.0f };
+
+ float v;
+ int i;
+ for ( i = 0; i < 10; i++ ) {
+ v = stdlib_base_acschf( x[ i ] );
+ printf( "acschf(%f) = %f\n", x[ i ], v );

+{{alias}}( x )
+ Computes the hyperbolic arccosecant of a single-precision floating-point
+ number.
+
+ The hyperbolic arccosecant is defined as
+
+ acsch(x) = asinh(1/x)
+
+ If `x` is zero, the function returns positive or negative infinity,
+ depending on the sign of `x`.
+
+ Parameters
+ ----------
+ x: number
+ Input value.
+
+ Returns
+ -------
+ y: number
+ Hyperbolic arccosecant.
+
+ Examples
+ --------
+ > var y = {{alias}}( 1.0 )
+ ~0.8814
+
+ > y = {{alias}}( -1.0 )
+ ~-0.8814
+
+ > y = {{alias}}( 0.0 )
+ Infinity
+
+ > y = {{alias}}( NaN )
