Converts the argument to a {@code long} by an unsigned
conversion. In an unsigned conversion to a {@code long}, the
high-order 48 bits of the {@code long} are zero and the
low-order 16 bits are equal to the bits of the {@code short} argument.
Consequently, zero and positive {@code short} values are mapped
to a numerically equal {@code long} value and negative {@code
short} values are mapped to a {@code long} value equal to the
input plus 2<sup>16</sup>.
@param x the value to convert to an unsigned {@code long}
@return the argument converted to {@code long} by an unsigned
conversion
