sum method in functor chain creates too large values

[PrometheusPi]

Using the ISAAC dev and vector field visualization of the E_y component results in extremely high numbers which can not be dealt with in the functor chain:

Please be aware that min/max values are reversed - might be an overflow issue.

Likely, the numbers seem to be max finite float value

Might be a division by zero if we chose a single component of the vector fields in the functor chain.
\vec{E} -> mul(0, 0.001, 0) | sum = E_y * 0.001
Since perhaps the same functor chain is used to extract the orientation of the line integral convolution (LIC).

I could create the same problem of really large numbers using the glowing gas pipeline - the error seems to originate from the sum method.
