5.11.8 EDIV (FNC 123)
Operation:
The floatin
g
point value of S
1
is divided b
y
the
floatin
g
point value of S
2
. The result of the division
is stored in D as a floatin
g
point value. No
remainder is calculated.
Points to note:
Points a, b, c, d of the EADD instruction appl
y
, except that a division is performed.
See pa
g
e 5-122.
•If S
2
is 0 (zero) then a divide b
y
zero error occurs and the operation fails.
5.11.9 ESQR (FNC 127)
Operation:
A square root is performed on the floatin
g
point
value of Sand the result is stored in D.
Points to note:
Points a, b, c, d of the EADD instruction appl
y
, except that a square root is performed.
See pa
g
e 5-122.
•If S is ne
g
ative then an error occurs and error fla
g
M8067 is set ON.
