Searching the minimum value of single-precision real number
EMIN(P)
These instructions search for the minimum value in the (n) point(s) of single-precision real number block data in the device
starting from the one specified by (s), and store the minimum value in the device areas specified by (d) and (d)+1.
These instructions also store the location of the first minimum value from (s) in the device specified by (d)+2 and the number
of minimum values in the device specified by (d)+3.
*1 The EMIN instruction is not supported by the ST language. Use MIN of the standard function.

Processing details
• These instructions search for the minimum value in the (n) point(s) of single-precision real number block data in the device
starting from the one specified by (s), and store the minimum value in the device areas specified by (d) and (d)+1. These
instructions also store the location of the first minimum value from (s) in the device specified by (d)+2 and the number of
minimum values in the device specified by (d)+3.
• The start of the block data in the device specified by (s) is counted as 1st point when the location is counted.
• The following values are stored in (d).
• When (n) is 0, the processing is not performed.
