arithType — Arithmetic type 'double' (default) | 'single' | 'Fixed'
Specify the arithmetic used during analysis. When the arithmetic input is not specified and
the filter System object is unlocked, the analysis tool assumes a double-precision

applies only to filter System objects with fixed-point properties.
