# SUBTRACT, MULTIPLY, DIVIDE

Other versions: 7.31 | 7.40 | 7.54

## Obsolete Syntax

SUBTRACT dobj1 FROM dobj2.
MULTIPLY dobj2 BY   dobj1.
DIVIDE   dobj2 BY   dobj1.

### Effect

These statements have the same effect as the statements

The content of dobj2

• has the content of dobj1 subtracted from it,
• or is multiplied by the content of dobj1,
• or is divided by the content of dobj1,

and the result is assigned to dobj2. The data objects dobj1 and dobj2 have to be numeric. Only data objects can be specified and no calls or other expressions. The calculation type is determined like an arithmetic expression.

Division by the value 0 is undefined and raises a handleable exception. The only situation where division by 0 does not raise an exception is if the dividend is also 0. Here, the result is set to 0.

Note

The statements shown here have been replaced by calculation assignments with the operators -=, *=, and /= in which the operands can also be specified as expressions.

Example

The variable n has the value 1.50 after the calculation statements. See also the example for the corresponding calculation assignments.

DATA n TYPE p DECIMALS 2.

SUBTRACT 2 FROM n.
MULTIPLY n BY 3.
DIVIDE n BY 4.

### Handleable Exceptions

CX_SY_ARITHMETIC_OVERFLOW

• Cause: Overflow in arithmetic operation (type p)
Runtime error: BCD_OVERFLOW
• Cause: Integer overflow in addition
Runtime error: COMPUTE_INT_PLUS_OVERFLOW

CX_SY_CONVERSION_OVERFLOW

• Cause: Overflow in arithmetic operation (type p, with specified length)
Runtime error: BCD_FIELD_OVERFLOW

CX_SY_ZERODIVIDE

• Cause: Division by 0 (type p)
Runtime error: BCD_ZERODIVIDE
• Cause: Division by 0 (type f)
Runtime error: COMPUTE_FLOAT_ZERODIVIDE
• Cause: Division by 0 (type i)
Runtime error: COMPUTE_INT_ZERODIVIDE

### Non-Handleable Exceptions

• Cause: p field does not contain the correct BCD format
