> It seems I found out the reason why it cannot open. Null value (Nodata) of this image is -3.4028234663e+038. Pixel type is float-point, 32 bit. So the number is out of range of float-point. So how can I set null value into 0. Is there any way to do this in IDL.

IDL> help,-3.4028234663e+038
<Expression> FLOAT = -3.40282e+38

IDL seems to be fine with representing that number as a float. It probably will not keep all the decimals, though.
