1: Inverse conversion by sequential search
2: Positive conversion by binary search
3: Inverse conversion by binary search

(1) 32-bit integer type scaling calculates the output value from the set input value
based on the scaling conversion data where a maximum of 2000 points data ((X
Y ) to (X , Y ), N: the number of points) are defined.
0 N-1 N-1
The point data corresponding to the input value should be set in ascending order.
(Positive conversion: X
(2) The calculation method for output value is the same as 16-bit integer type scaling.
(Refer to Section 5.16.1.)
POINT
When the input value is outside the scaling conversion data or calculation result of
output value is outside the range of -2147483648 to 2147483647, an operation
error will occur.
