You could do something like below which will allow you to
serialize any number.
````
import std.stdio : writeln;
import std.traits : isNumeric;
ubyte[] bytes(T)(T num) if (isNumeric!T) {
auto buf = new ubyte[T.sizeof];
(*cast(T*)(buf.ptr)) = num;
return buf;
}
T value(T)(ubyte[] buf) if (isNumeric!T) {
return (*cast(T*)(buf.ptr));
}
````
And example usage:
````
double foo = 3.14;
writeln(foo); // Prints 3.14
ubyte[] bar = foo.bytes;
writeln(bar); // Prints the bytes equal to 3.14
foo = bar.value!double;
writeln(foo); // Prints 3.14
````
Regarding the test assertion that failed. Turns out I had a bug
in the test. (of course)
This last solution is very pretty. Thanks.
You folks are all so kind!
