[half_float] parsing error

Hi, I can´t understand why my data is not parsed. I got this on my logs:

status"=>400, "error"=>{"type"=>"mapper_parsing_exception", "reason"=>"failed
to parse field [MyFIELD-NAME] of type [half_float] in document with id '2-17546231'. Preview of field's value: '73925.0'", "caused_by"=>{"type"=>"illegal_argument_exception", "reason"=>"[half_float] supports only finite values, but got [73925.0]"}

half_float supports 65535 as max number, another type is needed to hold this value.
