Result of comparing x
with y
.
Result of comparing x
with y
. Returns NaN if operands
are not comparable. If operands are comparable, returns a
Double whose sign is:
- negative iff x < y
- zero iff x === y
- positive iff x > y
Returns Some(x) if x >= y, Some(y) if x < y, otherwise None.
Returns Some(x) if x >= y, Some(y) if x < y, otherwise None.
Returns Some(x) if x <= y, Some(y) if x > y, otherwise None.
Returns Some(x) if x <= y, Some(y) if x > y, otherwise None.

.
Result of comparing x
with y
. Returns None if operands
are not comparable. If operands are comparable, returns Some[Int]
where the Int sign is:
- negative iff x < y
- zero iff x == y
- positive iff x > y
Interval partial order defined as follows:
I <= J if I is a subset of J.
