Arithmetric Types

The parameter ARITH_TYPE determines how PV and the compensation terms (t) are combined.
User may select from nine (9) commonly used math functions, depicted below. COMP_HI and
COMP_LO are compensation limits.

If there is a divide by zero and the numerator is positive, f is set to COMP_HI; if the numerator is
negative, then f is set to COMP_LO.

The square root of a negative value will equal the negative of the square root of the absolute
value. Imaginary roots are not supported.

If there is a divide by zero and numerator is positive, f will be limited to COMP_HI; if the
numerator is negative, f will be limited to COMP_LO. Compensation inputs which are not usable
are not included in the calculation. PV is always included.
