F represents a floating-point value. There is a decimal point in a
floating-point value.
Only the 32-bit instructions DEZCP and DEZCPP are valid.

Explanation
 S
1
: Minimum binary floating-point value; S
2
: Maximum binary floating-point
value; S: Binary floating-point value; D: Comparison result (D occupies three
consecutive devices.)
 The instruction is used to compare the binary floating-point value in S with that
in S
1
, and compare the binary floating-point value in S with that in S
2
. The
comparison result is stored in D.
 If S
1
is a floating-point value, the instruction will be used to compare S
1
with the
binary floating-point value in S
2
. If S
2
is a floating-point value, the instruction
will be used to compare the binary floating-point value in S
1
with S
2
.
 If the binary floating-point value in S
1
is greater than that in S
2
, the binary
floating-point value in S
1
will be taken as the maximum/minimum value during
the execution of the instruction EZCP.
Example
 If the operand D is M0, M0, M1, and M2 will be occupied automatically.
 When X0 is ON, the instruction DEZCP is executed, and M0, M1, or M2 is ON.
When X0 is OFF, the execution of the instruction DEZCP stops, and the states
of M0, M1, and M2 remain unchanged.
 If users want to reset M0, M1, or M2, they can use the instruction RST or
ZRST.

If the value in (D1, D0) >the value in (D21, D20) , M0 will be ON.
If the value in (D1, D0) <the value in (D21, D20) <the value in (D11, D10),
M1 will be ON.
If the value in (D21, D20) >the value in (D11, D10), M2 will be ON.
