Interval

An interval [a,b] along the real line, where either endpoint may be infinite.

struct Interval (

) if (

isSigned!T

) {

}

Members

contains bool contains(X x): Check whether the value x is contained in the interval, i.e. whether a <= x <= b or b <= x <= a.
order void order(): If a > b, swap the endpoints.

isInfinite bool isInfinite [@property getter]

Determine whether the interval is infinite. This is true if:

If T is an integer type, this is always false.

isOrdered bool isOrdered [@property getter]

Determine whether this is an ordered interval, i.e. whether a <= b.

length T length [@property getter]

The length of the interval, defined as b-a.

auto i1 = interval(1, 5);
assert (i1.length == 4);

auto i2 = interval(0, real.infinity);
assert (i2.isInfinite);
