GetFeatureInfo doesn’t round scales

Description:

(Following the mailing list thread)
I have a layer with a threshold set to 1:40,000.

When I query it with GetFeatureInfo it doesn’t work:

http://wppgeog3/geoserver/ows?buffer=5&LAYERS=OS_CP_POLYGON_POSTCODES&QUERY_LAYERS=OS_CP_POLYGON_POSTCODES&STYLES=&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetFeatureInfo&BBOX=427188.8%2C261509.2%2C438456%2C270234&FEATURE_COUNT=50&HEIGHT=779&WIDTH=1006&FORMAT=image%2Fpng&INFO_FORMAT=application%2Fvnd.ogc.gml&SRS=EPSG%3A27700&X=454&Y=362

GeoServer tells me that scale is 40,000.000000000044.

If I change the layer threshold to 1:40,001 the GetFeatureInfo works.

Conversely a GetMap request works out to at least 40,017 for the same layer.

Ideally GetFeatureInfo requests would be as flexible as GetMap requests, but at the very least they should use “round()” before comparing scales to mitigate this issue.
