/// @assertion int toUnsigned(int width)
/// Returns the least significant width bits of this integer as a non-negative
/// number (i.e. unsigned representation). The returned value has zeros in all
/// bit positions higher than width.
/// ...
/// If the input fits in width bits without truncation, the result is the same as
/// the input. The minimum width needed to avoid truncation of x is given
/// by x.bitLength, i.e.
///
/// x == x.toUnsigned(x.bitLength);
/// @description x == x.toUnsigned(x.bitLength);
