5.11.6 EAUB (FNC 121)
Operation:
The floatin
g
point value of S
2
is subtracted from the
floatin
g
point value of S
1
and the result stored in
destination device D.
Points to note:
All points of the EADD instruction appl
y
, except that a subtraction is performed.

5.11.7 EMUL (FNC 122)
Operation:
The floatin
g
point value of S
1
is multiplied with the
floatin
g
point value of S
2
. The result of the
multiplication is stored at D as a floatin
g
point
value.
Points to note:
Point a, b, c and d of the EADD instruction appl
y
, except that a multiplication is performed.
