FUN 041

DIV

Unsigned double/single division

Expression

Input -[ A+1×A DIV B ® C ]- Output

Function

When the input is ON, the double-word data of A+1×A is divided by the data of B, and the quotient is stored in C and the remainder in C+1. The data range of A+1×A is 0 to 4294967295, and the data range of B and C is 0 to 65535.

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

Example

When R010 is ON, the double-word data of D0201×D0200 is divided by the constant data 4000, and the quotient is stored in D1000 and the remainder is stored in D1001.

If the data of D0201×D0200 is 332257, the quotient 83 is stored in D1000 and the remainder 257 is stored in D1001.

Note

·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.
