Description
When the execution condition is OFF, DIVL(57) is not executed. When the exe-
cution condition is ON, DIVL(57) the eight-digit content of Dd and D+1 is divided
by the content of Dr and Dr+1 and the result is placed in R to R+3: the quotient in
R and R+1, the remainder in R+2 and R+3.

Flags
ER:
Dr and Dr+1 contain 0.
Dd, Dd+1, Dr, or Dr+1 is not BCD.
Indirectly addressed DM word is non-existent. (Content of *DM word is
not BCD, or the DM area boundary has been exceeded.)
EQ:
ON when the result is 0.

Limitations
Dr and Dr+1 cannot contain zero. Dr and Dr+1 must be in the same data area, as
must Dd and Dd+1; R and R+1.
The dividend and divisor must be between 0.0000001 x 10
–7
and
0.9999999 x 10
7
. The results must be between 0.1 x 10

.
Description
When the execution condition is OFF, FDIV(79) is not executed. When the exe-
cution condition is ON, FDIV(79) divides the floating-point value in Dd and Dd+1
by that in Dr and Dr+1 and places the result in R and R+1.
