GPS accuracy of Android Emulator

I am developing a website which used W3C GeoLocation API to obtain users' position. I try to run the website in Android Emulator and use DDMS / geo fix to send the coordinate to the device. However the coordinate received is inaccurate. For exam开发者_开发技巧ple, (22.377127, 114.095535) will become (22.370335, 114.08523353). I try to run some Android GPS example from Internet, and the results is just the same. I can certainly say that this is not my program bug. From my observation, it seems like some rounding problem. Can anybody help? Thanks.

My Environment: Windows 7 Professional 64bit Android 2.2 with Google API (API level 8)

I notice the same problem. I send lon, lat -83.0000, 40.000 via DDMS and the emulator app receives and -83.013833, 40.006666.
