[Gdal-dev] Does gdalinfo Bounding Box Information really match DTED / SRTM ?

I use gdalinfo to extract bounding box information of DTED L0&L1 (dt0, dt1)
as well as SRTM (hgt over bil+hdr+proj solution) data.
In both cases the reported corner points are not integer values as supposed. 

Corner Coordinates: (DTED)
Upper Left  (  -0.0041667,  49.0041667) (  0d 0'15.00"W, 49d 0'15.00"N)
Lower Left  (  -0.0041667,  47.9958333) (  0d 0'15.00"W, 47d59'45.00"N)
Upper Right (   1.0041667,  49.0041667) (  1d 0'15.00"E, 49d 0'15.00"N)
Lower Right (   1.0041667,  47.9958333) (  1d 0'15.00"E, 47d59'45.00"N)
Center      (   0.5000000,  48.5000000) (  0d30'0.00"E, 48d30'0.00"N)

Is this is a roundig bug of gdal or are the data sources just coded like
this ?
