Parameters

Input

s1 (REAL)

Real number data for multiplicand.

s2 (REAL)

Real number data for multiplier.

Output

d (REAL)

32-bit area for result (destination).

Remarks

• If the required data type is supported, we recommend using the IEC instruction MUL.

• This instruction cannot be programmed in the interrupt program.

Error flags

sys_bIsOperationErrorHold (turns to TRUE and remains TRUE)

if data other than real number data is specified in s1 and s2.

sys_bIsOperationErrorNonHold (turns to TRUE for one scan)
