Function std.experimental.checkedint.Saturate.onLowerBound
Implements saturation for operators +=, -=, *=, /=, %=, ^^=, &=, |=, ^=, <<=, >>=,
and >>>=. This hook is called if the result of the binary operation does
not fit in Lhs without loss of information or a change in sign.
T onLowerBound(Rhs, T)
(
Rhs rhs,
T bound
);
Parameters
| Name | Description |
|---|---|
| Rhs | The right-hand side type in the assignment, after the operation has been computed |
| bound | The bound being violated |
Returns
Lhs if rhs >= 0, Lhs otherwise.
Example
auto x = checked!Saturate(short(100));
x += 33000;
writeln(x); // short.max
x -= 70000;
writeln(x); // short.min
