The binary floating-point value in
S
2
is subtracted from the binary
floating-point value in
S
1
, and the difference is stored in
D
.

If
S
1
is a floating-point value, the instruction will be used to subtract the
binary floating-point value in
S
2
from the floating-point value. If
S
2
is a
floating-point value, the instruction will be used to subtract the
floating-point value from the binary floating-point value in
S
1
.
S
1
and
S
2
can be the same register. If the instruction DESUB is used
under the circumstances, the value in the register is subtracted from
itself whenever the conditional contact is ON in a scan cycle. Generally,
the pulse instruction DESUBP is used.
If the absolute value of an oepration result is greater than the maximum
floating-point value available, a carry flag will be ON.
If the absolute value of an oepration reuslt is less than the minimum
floating-point value available, a borrow flag will be ON.
If an operation result is 0, a zero flag will be ON.
SM1064 is the zero flag in an Ox motion subroutine, and SM968 is the
zero flag in O100.
SM1065 is the borrow flag in an Ox motion subroutine, and SM969 is the
borrow flag in O100.
SM1066 is the carry flag in an Ox motion subroutine, and SM970 is the
carry flag in O100.

When X0.0 is ON, the binary floating-point value in (D3, D2) is
subtracted from the binary floating-point value in (D1, D0), and the
difference is stored in (D11, D10).
