sio2CameraRender

Hi - I just found out about this engine last night. After skimming the source, I noticed this snippet in sio2CameraRender and since there are not comments anywhere in sight (!), and I'm not up on my coffee intake for the day yet, what does this do? It seems to be taking the decimal part of the Z of the camera position and adding it to half the 'height'... Why?

Thanks

Code:

      precision = ( float )( int )( _SIO2camera->mat[14] *= 1000.0f );
      _SIO2camera->mat[14] = ( float )( precision / 1000.0f ) + _SIO2camera->height * 0.5f;

cut off some number after 0.000 . such as 0.0003432 will be cuted the tail

anything wrong with round()?
Oh now I see you are keeping precision to 3 decimal places.
How odd.
