function blocks provide universal arithmetic
capability. As shown in the block diagram, each input has
gain and bias scaling. The resulting signals are then applied
to configurable math operations (DIV, MUL, ADD and
SUB). Operation A will be performed first on inputs A and
B. Operation B will be performed next on the resultant and
input C.
Unused inputs to a MUL or DIV operation will be set to 1.0
and those to an ADD or SUB operation will be set equal to
0.0. The operation of those inputs will function normally
so it is important to insure that the bias and gain settings are
set properly.
In a DIV operation, when a divisor is 0.0 the output will go
to the maximum Real number with the sign determined by
the numerator. If the numerator is 0 the output will be 0.
