compareTo method
Compares this object to another object.
Returns a value like a Comparator when comparing this
to other
.
That is, it returns a negative integer if this
is ordered before other
,
a positive integer if this
is ordered after other
,
and zero if this
and other
are ordered together.
The other
argument must be a value that is comparable to this object.
Implementation
@override
int compareTo(Complex other) {
// Performing == on floating point values is not numerically stable.
//
// Instead, '>' and '<' are more reliable in terms of machine precision so
// 0 is just a fallback.
if (abs() > other.abs()) {
return 1;
}
if (abs() < other.abs()) {
return -1;
}
return 0;
}
