Description
Data type of result
(S1) Augend
data
(S2) Addend
data
Data type of (S1) or (S2)
which is greater
[Functions]
(1) The data specified with (S2) is added to the data specified with (S1).
(2) When (S1) and (S2) differ in data type, the data of the smaller data type is
converted into that of the greater type before operation is performed.
[Errors]
(1) An operation error will occur if:
• (S1) or (S2) is an indirectly specified device and its device No. is outside the
range.
[Program examples]
(1) Program which substitutes the result of adding K123 and #0 to W0
W0 = K123 + #0
(2) Program which substitutes the result of adding #0F and #10 to D0L
D0L = #0F + #10

The 64-bit floating-point type data are used for addition, and the result is
converted into the 32-bit integer type and then substituted.
