
S
: the designated source value.
D
: the SIN value result.

S
is the designated source in radians.
 The value in radians (RAD) is equal to (angle × π /180).
 The SIN obtained from the source value designated by
S
is stored in
D
.

When X0=On, the SIN value of the designated binary floating point number (D1,
D0) in radians (RAD) will be stored in (D11, D10), with the content consisting of a
binary floating point number.
