5.8.9 Function Generator (FGN)
( 1 ) Operation
The FGN instruction generates a function based on the parameters specified in the parameter table. It then uses the
function to calculate output value Y based on the value of input X.
The FGN instruction will be for integers, double-length integers, or real numbers, depending on the data type of input
value X. The structure of the parameter table changes accordingly.
ΠCreate the parameter table so that X
1
< X
2
< ... < X
N
.
Output value Y is calculated from
input value X for the function
generated by the parameter table.
