What will the calculated field return for a value of " " in the case of crm_user_total_spent set as a double?

In the context of calculated fields in Adobe Experience Platform, a value of " " represents an empty string. When a field is set as a double, it is typically designed to handle numerical values. An empty string does not equate to a valid numerical representation. Therefore, when " " is evaluated in a context that expects a double, it is interpreted as an absence of a valid number rather than a numeric value.

In many programming and data processing environments, the expected behavior when encountering an empty string in such calculations is to return a value that denotes the absence of data but does not equate to a traditional null. Instead, the system will recognize the empty input and return that there is "no data" or "empty" for that calculation. As a result, if " " is processed in a way that the field expects a double, it would generally yield an empty return indicating that no valid double value was derived.

This contrasts with an actual null, which indicates that the field has never been assigned a value at all, whereas " " has been assigned a value but is not usable as a double. So, the calculated field treating " " as an empty return aligns with the option selected.
