When creating a Feature where the Value Type is number, if I set the value to be 
1.0
it still saves it as 
intValue
instead of 
doubleValue
. If I set the value to be 
1.01
it saves it as 
doubleValue
. Is there any way to set the number Value Type to be 
doubleValue
for a value of 
1
or 
1.0
?

hey vincent, are you talking about saving it in the dashboard somewhere? where are you seeing the results as an int value instead of a double? is this related to any of the SDK's or the growthbook dashboard?
j
Hi Tina, I'm talking about the values saved in the Features tab of the GrowthBook web UI. I see them returned as INT values from the GrowthBook SDK

thanks for clarifying. we do have a team member looking into this right now and can confirm the issue you describe. while it doesn't look ideal, when using it in an SDK, it should not present a problem, it's just not ideal to see the wrong precision in the UI. cc @happy-autumn-40938

I want to say that the UI was actually displaying it correctly as 
1.0
, but the SDK was returning the INT value of 
1
h
to be clear, we're talking about the value applied (forced), not the rule used to evaluate?
b
in our SDK's that are in languages that are not strictly typed, i imagine this will be an issue. i'm guessing you're using either JS, ruby or python? please confirm
j
I'm talking about this Default value here and the Forced Value:
I believe we are using the C# SDK
b
might be worth it for us to create a ticket @happy-autumn-40938 to not coerce float values to integers in the JSON generator section we were talking about. it's likely to cause an issue in numerous SDKs

@jolly-journalist-68574 as a workaround, it might make sense to format the number in your view with the required level of precision instead of relying on the evaluated value
j
Thank you for the ticket. @better-magician-65629 I'm not quite sure what your last suggestion meant, could you elaborate? What did you mean by "format the number in your view"
h
I think generally we're wondering whether you're able to coerce the evaluated flag value into the number format that your app requires (int, double, etc). Generally it would be best to have an opinionated type for this value within your app and not rely on the SDK payload format.
b
the value that will be displayed to users. for example, if using javascript:
Copy code
const value = growthbook.getFeatureValue('my_float_value', 0) // => 1
const displayValue = value.toFixed(2) // => '1.00'
i'm looking at the C# SDK now, it looks like the 
GetFeatureValue<T>()
method is genericized. can you pass in your desired type, e.g. Double, and how does it behave? this signature looks similar to the java SDK, and in java we coerce the value to the desired number type. wondering if the C# SDK behaves similarly.
i ddi further digging, it looks like it's implementing newstonsoft 
JToken.ToObject<T>
and it should probably be coerced for you, similar to how i described the behaviour of the java SDK. https://www.newtonsoft.com/json/help/html/M_Newtonsoft_Json_Linq_JToken_ToObject__1.htm
can you clarify which C# SDK methods you're using?
