| * @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); |
