*Example*
|
||
|
|
|
||
|
|
[source.merge.styled,esql]
|
||
|
|
----
|
||
|
|
include::{esql-specs}/floats.csv-spec[tag=to_double-str]
|
||
|
|
----
|
||
|
|
[%header.monospaced.styled,format=dsv,separator=|]
|
||
|
|
|===
|
||
|
|
include::{esql-specs}/floats.csv-spec[tag=to_double-str-result]
|
||
|
|
|===
|
||
|
|
|

|
|
Note that in this example, the last conversion of the string isn't possible.
|
||
|
|
When this happens, the result is a *null* value. In this case a _Warning_ header is added to the response.
|
||
|
|
The header will provide information on the source of the failure:
|
||
|
|
|
||
|
|
`"Line 1:115: evaluation of [TO_DOUBLE(str2)] failed, treating result as null. Only first 20 failures recorded."`
|
||
|
|
|
||
|
|
A following header will contain the failure reason and the offending value:
|
||
|
|
`"java.lang.NumberFormatException: For input string: "foo""`
|
||
|
|
|
