digitalmars.D.learn - JSONValue floating and 42

Hi,

I have to deal with a JSON like this
[{"value":42},{"value":1e+100}]

Value is a floating number, but the providing system does not 
write 42 as 42.00.
While trying to get the value with .floating, I get an exception 
because 42 is not
a floating value.

I try to understand what is the issue here.

-> Does the system violates the JSON Standard, and it should 
deliver 42.00?
-> .floating should be enhanced to handle 42?
-> I need to analyze every value whether it is a floating or an 
integer?

Kind regards
André

This is the correct option. Something like:

double f;
if (j["value"].type == JSON_TYPE.INTEGER)
   f = j["value"].integer.to!float;
else
   f = j["value"].floating;

There are also a number of libraries available that make dealing 
with json a bit easier:
code.dlang.org/search?q=json

I will do so. Thanks.
