I have debug the code of kernel. There is no problem.
This problem should be a problem of console, float is not correctly parsed after being passed to go-console

[jackwener]

go-console or other display area should invoke the right parseFloat/showFloat().

The float number we get from rowreaderv2 (storage) is 0x400ccccd.

The result of graph service also is it.

It depend on how to show/parse the result 0x400ccccd
