(Note 7) Can be specified only when the operation unit is a single-precision floating point real number (SF).
(Note 8) Can be specified only when the operation unit is a double-precision floating point real number (DF).

Outline of operation
● This instruction searches the range specified by [S2] and [S3] for the search data specified
by [S1].
● The search result is given in the data format of unsigned 32-bit integer, and stored as
follows.
[D], [D]+1
[D]+2、[D]+3
16-bit device
[D]
[D]+1
32-bit device
Store the number of data with the same value in a
decimal form
Store the position of the first matching data
(relative position with the first data as '0')
Description of output
● The maximum amount of data that can be specified is 30000.
● Search is executed from [S2] to [S3].
