
The instruction is used to convert a binary integer into a binary
floating-point number.

S : Source device; D : Conversion result
1. If the absolute value of the converesion result is greater than the
maximum floating-point value avaliable, a carry flag will be ON.
2. If absolute value of the conversion result is less than the mimum
floating-point vlaue available, a borrow flag will be ON.
3. If the conversion 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 X1.1 is ON, the binary integer in (D1, D0) is converted into a
binary floating-point number, and the conversion result is stored in
(D21, D20).

Suppose the value in the 32-bit register (D1, D0) is K100,000. When
X1.1 is ON, K100,000 is converted into the 32-bit floating-point number
16#4735000, and 16#4735000 is stored in the 32-bit register (D21,
D20).
