Explanation
 Whether the source value in S
is a radian or a degree depends on the state of
a radian/degree flag.
 S: Source value; D: Sine value
 If a radian/degree flag is OFF, the source value in S is a radian.
Radian=Degree×π /180.
 If a radian/degree flag is ON, the source value in S is a degree.

 If an operation result is 0, a zero flag will be ON.
 The sine of the source value in S is stored in D.
The relation between radians and sine values is shown below.

Example 1
 A radian/degree flag is reset to OFF. The binary floating-point value in (D1, D0)
is a radian. When X0 is ON, the sine of the binary floating-point value in (D1,
D0) is stored in (D11, D10).
