EDIV D10 D20 D50
S1· S2· D·
X0
The floating point value of S1 is divided by the floating point value of S2. The result of the
division is stored in D as a floating point value.
If a constant K or H used as source data, the value is converted to floating point before the
division operation.
EDIV D100 K100 D110
X1
The source data S2 is 0, the calculation will be error. The instruction will not work.
Note: the operand value must be floating numbers, otherwise the result will be error.
