Notes:

The order of the x parameters should be x
1
< x
2
< ... < x
i
< ... < x
n
. In other words, the
data table should be constructed so the X values go from lowest value for X
1
to the
highest value for X
n
.

If input value in Register A is smaller than x1, then y1 is given as f(x). In this example, if
XW04 is less than D0600 (-2000), then value in D0100 would be D0604 data (-1800).

Similarly, if input value in Register A is greater than xn, then yn is given as f(x). In this
example, if XW04 is greater than D0603 (2000), then value in D0100 would be D0607
data (1800).

The valid data range is -32768 to 32767.
