F32_DIV

Redundant instruction

NOTE

This is a redundant instruction. It is replaced by: DIV

The 16-bit data or 16-bit equivalent constant specified by s1 is divided by the 16-bit data or 16-bit equivalent constant specified by s3 if the trigger EN is in the ON-state.

Parameters

Input

s1 (WORD, INT, UINT): Dividend
s2 (WORD, INT, UINT): Divisor

Output

d (WORD, INT, UINT): Quotient

The variables s1, s2 and d have to be of the same data type.

Example

(1) Example value 36
(2) Example value 17
(3) Result value 2 if trigger is ON
(4) Remainder 2 stored in DT9015/90015

Remarks

Instead of using this F instruction, we recommend using the corresponding FP7 instruction: FP_DIV_MOD
If the required data type is supported, we recommend using the IEC instruction DIV.
The quotient is stored in d and the remainder is stored in the system variable sys_iDivRemainder. All 16-bit values are treated as integer values.

Error flags

sys_bIsEqual (turns to TRUE for one scan): if the calculated result is 0.
sys_bIsCarry (turns to TRUE for one scan): if the negative minimum value -32768 (16#8000) is divided by -1 (16#FFFF)
