Signed integer division rounds to
Describe how your compiler for the hardware rounds the result of dividing two signed integers.

Choose this option if neither
Floordescribes the compiler behavior, or if that behavior is unknown.
If the quotient is between two integers, the compiler chooses the integer that is closer to zero as the result.
If the quotient is between two integers, the compiler chooses the integer that is closer to negative infinity.
To simulate rounding behavior of the C compiler that you use to compile generated code, use the Integer rounding mode parameter for blocks. This setting appears on the Signal Attributes pane of the parameter dialog boxes of blocks that can perform signed integer arithmetic, such as the Product block.
For most blocks, the value of Integer rounding mode completely defines rounding behavior. For blocks that support fixed-point data and the
Simplestrounding mode, the value of Signed integer division rounds to also affects rounding. For details, see Rounding (Fixed-Point Designer).
For more information on how this parameter affects code generation, see Hardware Implementation Options (Simulink Coder).
This table lists the compiler behavior described by the options for this parameter.
