Hi, everybody here, I am a pretty fresh user of Houdini, there are some questions which really confuse me a lot, for example, there's very simple scene:

I tried to manipulate a sphere to move along the Y-axis with the function sin($F*9), and I also load two font sop in the scene to display the number info of the sphere movement, one font sop access the channel with `chs("/obj/geo1/xform1/ty")`, it was automatically filled when I choose the paste the copied relative reference, another one is with `ch("/obj/geo1/xform1/ty")`, the results from the two nodes are a little bit different, the result from the first font sop is with 17 digits on the decimal part and another one is only 6 digits, could any one help me to explain why they are different like this way? thanks a lot.
