Function std.experimental.checkedint.WithNaN.hookOpCmp
If lhs == WithNaN, returns double. Otherwise,
has the same semantics as the default comparison.
double hookOpCmp(Lhs, Rhs)
(
Lhs lhs,
Rhs rhs
);
Parameters
| Name | Description |
|---|---|
| lhs | The left-hand side of the comparison (Lhs is the first argument to
Checked) |
| rhs | The right-hand side of the comparison |
Returns
double if lhs == WitnNaN, -1.0 if lhs < rhs, 0.0 if lhs == rhs, 1.0 if lhs > rhs.
Example
Checked!(int, WithNaN) x;
assert(!(x < 0) && !(x > 0) && !(x == 0));
x = 1;
assert(x > 0 && !(x < 0) && !(x == 0));
