Function std.conv.unsigned
Returns the corresponding unsigned value for x
(e.g. if x
has type
int
, it returns cast(uint) x
). The advantage compared to the cast
is that you do not need to rewrite the cast if x
later changes type
(e.g from int
to long
).
auto unsigned(T)
(
T x
)
if (isIntegral!T);
auto unsigned(T)
(
T x
)
if (isSomeChar!T);
Note that the result is always mutable even if the original type was const
or immutable. In order to retain the constness, use Unsigned
.
Example
import std .traits : Unsigned;
immutable int s = 42;
auto u1 = unsigned(s); //not qualified
static assert(is(typeof(u1) == uint));
Unsigned!(typeof(s)) u2 = unsigned(s); //same qualification
static assert(is(typeof(u2) == immutable uint));
immutable u3 = unsigned(s); //explicitly qualified
