iterAcosh
Create an iterator which iteratively computes the hyperbolic arccosine.
Usage
var iterAcosh = require( '@stdlib/math/iter/special/acosh' );
iterAcosh( iterator )
Returns an iterator which iteratively computes the hyperbolic arccosine.
var array2iterator = require( '@stdlib/array/to-iterator' );
var it = iterAcosh( array2iterator( [ 1.0, 2.0 ] ) );
// returns <Object>
var r = it.next().value;
// returns 0.0
r = it.next().value;
// returns ~1.317
// ...
The returned iterator protocol-compliant object has the following properties:
- next: function which returns an iterator protocol-compliant object containing the next iterated value (if one exists) assigned to a
value
property and adone
property having aboolean
value indicating whether the iterator is finished. - return: function which closes an iterator and returns a single (optional) argument in an iterator protocol-compliant object.
Notes
- The domain of hyperbolic arccosine is restricted to
[1,+infinity)
. If an iterated value is outside of the domain, the returned iterator returnsNaN
. - If an iterated value is non-numeric (including
NaN
), the returned iterator returnsNaN
. If non-numeric iterated values are possible, you are advised to provide aniterator
which type checks and handles non-numeric values accordingly. - If an environment supports
Symbol.iterator
and a provided iterator is iterable, the returned iterator is iterable.
Examples
var uniform = require( '@stdlib/random/iter/uniform' );
var iterAcosh = require( '@stdlib/math/iter/special/acosh' );
// Create a seeded iterator for generating pseudorandom numbers:
var rand = uniform( 1.0, 10.0, {
'seed': 1234,
'iter': 10
});
// Create an iterator which consumes the pseudorandom number iterator:
var it = iterAcosh( rand );
// Perform manual iteration...
var r;
while ( true ) {
r = it.next();
if ( r.done ) {
break;
}
console.log( r.value );
}
