Error
To be set if FPU operation error flag of F0057E, F0057C, F0057B or F0057A is
set.
F110
1) RADD (Real Add)
(1) Saves the result of specified real number S1 and S2 added up in D area in real number. (real number is
occupied in 2-word)
(2) The range of operand’s value is as follows;
± 2
-126
≤ | Operand | < ± 2
128
If the result of operand’s value exceeds the range, operation error will occur. However, specific
value may be assigned there to keep continuous operation.

RADD
2) LADD (Long Real Add)
(1) Saves the result of specified Long Real number S1 and S2 added up in D area in Long Real number. (Long
Real number is occupied in 4-word)
(2) The range of operand’s value is as follows.
± 2
-1022
≤ | Operand | < ± 2
1024
If the result of operand’s value exceeds the range, operation error will occur. However, specific value
may be assigned there to keep continuous operation.
