Hey all,
I have one short question. Is:
the same as
if not, please can you explain the difference in your answer.
Thanks upfront.

Yes and no. They are both same data type, but var t_stop = 0.0 contains an actual value and var float t_stop = na does not. So you can see the difference when you try to plot the variables by themselves.

var float t_stop = na will display an empty box, and var t_stop = 0.0 will display a horizontal line at 0.0.

Thank you!
