Precautions
• The search method and the number of searches vary depending on whether SM755 is on or off.
• When the scaling conversion data is sorted in ascending order, the search method varies depending on the status of
SM755 and therefore the processing speed also varies. The processing speed depends on the number of searches and is
faster as the number of searches is less.

• Case in which the processing speed of sequential search is faster
When the coordinate point specified by (s1) is one from 1 to 15 while the number of coordinate points is the maximum, the number of sequential searches is
equal to or less than 15 and therefore the processing speed of the sequential search becomes faster.
• Case in which the processing speed of binary search is faster
The maximum number of searches is 32 and therefore when coordinate point 33 or later is specified by (s1), the number of binary searches is equal to or
greater than the number of sequential searches, and accordingly the processing speed of the binary search becomes faster.
(1) The processing speed of the binary search is faster because the number of sequential searches is less than the number of binary searches.
(2) The processing speed of the binary search is faster because the number of binary searches is less than the number of sequential searches.
Error code
(SD0)
Description
3405H
The X-coordinate data of the scaling conversion data before the point specified in (s1) is not sorted in ascending order.
(Note that this error is not detected when SM755 is on.)
The input value specified by (s1) is out of the range of the specified scaling conversion data.
The number of coordinate points starting from the device specified by (s2) is out of the range, 1 to 4294967295.
(s1)
(s1)
Number of coordinates = 32767
Number of sequential searches = 32767
Number of binary searches = 15
Number of sequential searches = 1
Number of binary searches = 15
