[Setting data]
Setting data Description Data type of result
(S1) Dividend data
(S2) Divisor data
Data type of (S1) or (S2)
which is greater
[Functions]
(1) The data specified with (S1) is divided by the data specified with (S2) to find a
quotient.
(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:
• (S2) is 0; or
• (S1) or (S2) is an indirectly specified device and its device No. is outside the
range.
[Program examples]
(1) Program which divides K456 by #0 and substitutes a quotient to W0
W0 = K456 / #0

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