Description
z The format of floating point number of Fatek-PLC follows the IEEE-754 standard. For detail explanation of
the format please refer to 5.3 (Numbering System) page 5-9.
z Performs the division of the data specified at Sa and Sb and writes the result to the registers specified by
register D when the division control input "EN" =1 or "EN↑" ( P instruction) from 0 to 1. If the result exceed
the range that the floating point number can be expressed(
±3.4*10
38
) then the error flag FO0 will be set
to 1 and the D register will be intact.
