Hi all,

I have to serialize an array like [0.0, 0.0, 0.0] to a Json 
object. During this process, the serializer creates a string of 
the array, but it creates "[0, 0, 0]", dropping the decimal. How 
can I stop this?

This depends on the library you are using for serialization, but 
0 and 0.0 are the same thing in json anyway so it shouldn't 
matter for data interchange.

Which lib you using?

It totally depends on the library. As Adam says, 0.0 and 0 are generally 
interchangeable, but reality says they are sometimes not (I have had my 
share of issues with vibe.d Json treating 1.0 as Json.Type.float_ and 1 
as Json.Type.int_, where it doesn't allow you to get the int version as 
a float).

It would help to have a better understanding of why you need the .0 to 
appear.

I had a similiar issue. For me the issue was, std json "floating" 
was raising an exception while reading e.g  number 1 instead of 
1.0.
Ths solution was to use "get!double" instead.

Kind regards
Andre
