Compute the hyperbolic arccosecant of a number.
var acsch = require( '@stdlib/math/base/special/acsch' );
Computes the hyperbolic arccosecant of x
.
var v = acsch( 0.0 );
// returns Infinity
v = acsch( -0.0 );
// returns -Infinity
v = acsch( 1.0 );
// returns ~0.881
v = acsch( -1.0 );
// returns ~-0.881
v = acsch( NaN );
// returns NaN
v = acsch( -Infinity );
// returns -0.0
v = acsch( Infinity );
// returns 0.0

Computes the hyperbolic arccosecant of a double-precision floating-point number.
double out = stdlib_base_acsch( 1.0 );
// returns ~0.881
The function accepts the following arguments:
- x:
[in] double
input value.
