FUN 041
DIV
Unsigned double/single division
Expression
Input − [ A+1⋅A DIV B → C ]− Output
Function
When the input is ON, the
If the quotient is greater than 65535 (overflow), the limit value 65535 is stored in C, 0 is stored in C+1, and the instruction error flag (ERF = S051) is set to ON.
Execution condition
Input | Operation | Output | ERF |
OFF | No execution | OFF | − |
ON | Normal execution (B ≠ 0) | ON | − |
| Overflow (B ≠ 0) | ON | Set |
| No execution (B = 0) | OFF | Set |

•If divisor (operand B) is 0, ERF (instruction error flag = S051) is set to ON. The ERF (S051) can be reset to OFF by user program, e.g. − [ RST S051 ]− .
•This instruction handles the register data as unsigned integer.
