Processing details
• The data specified with (S1) is divided by the data specified with (S2) to find a quotient.
• 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.
Operation error
An operation error will occur if:
• (S2) is 0.
• (S1) or (S2) is an indirectly specified device and its device No. is outside the range.
Program example
■Program which divides K456 by #0 and substitutes a quotient to W0
W0 = K456 / #0
W0 3
■Program which divides #0F by #10 and substitutes a quotient to D0L
D0L = #0F / #10
D1 D0
D0L 100
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.
