// MAIN //

/**
* Returns an iterator which iteratively computes the half-value coversed sine.
*
* ## Notes
*
* -   If an environment supports `Symbol.iterator` **and** a provided iterator is iterable, the returned iterator is iterable.
*
* @param {Iterator} iterator - input iterator
* @throws {TypeError} must provide an iterator protocol-compliant object
* @returns {Iterator} iterator
*
* @example
* var uniform = require( '@stdlib/random/iter/uniform' );
*
* var iter = iterHacoversin( uniform( 0.0, 6.28 ) );
*
* var v = iter.next().value;
* // returns <number>
*
* v = iter.next().value;
* // returns <number>
*
* v = iter.next().value;
* // returns <number>
*
