compareTo method

  1. @override
int compareTo(
  1. Fraction other
)
override

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(Fraction other) {
  // I don't perform == on floating point values because it's not reliable.
  // Instead, '>' and '<' are more reliable in terms of machine precision so
  // 0 is just a fallback.
  if (toDouble() < other.toDouble()) {
    return -1;
  }

  if (toDouble() > other.toDouble()) {
    return 1;
  }

  return 0;
}
