toSigned abstract method
Returns the least significant width
bits of this integer, extending the
highest retained bit to the sign. This is the same as truncating the value
to fit in width
bits using an signed 2-s complement representation. The
returned value has the same bit value in all positions higher than width
.
If the input value fits in width
bits without truncation, the result is
the same as the input. The minimum width needed to avoid truncation of x
is x.bitLength + 1
, i.e.
x == x.toSigned(x.bitLength + 1);
Implementation
IntX toSigned(int width);
