/**
 * Returns the floating-point value adjacent to {@code f} in

 * semantically equivalent to {@code nextAfter(f,
 * Float.POSITIVE_INFINITY)}; however, a {@code nextUp}
 * implementation may run faster than its equivalent
 * {@code nextAfter} call.
 *
 * <p>Special Cases:
 * <ul>
 * <li> If the argument is NaN, the result is NaN.
 *
 * <li> If the argument is positive infinity, the result is
 * positive infinity.
 *
 * <li> If the argument is zero, the result is
 * {@link Float#MIN_VALUE}
 *
 * </ul>
 *
 * @param f starting floating-point value
 * @return The adjacent floating-point value closer to positive
 * infinity.
