  * Returns an iterator which iteratively evaluates the relative error exponential.
  *
  * ## 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 = iterExpm1rel( uniform( -50.0, 50.0 ) );
  *
  * var v = iter.next().value;
  * // returns <number>
  *
  * v = iter.next().value;
  * // returns <number>
  *
  * v = iter.next().value;
  * // returns <number>
