Gain parameters inherit a built-in integer type that is lossless
Description
The data type of the gain parameter is a built-in integer when the following conditions are met.
The input type is a built-in integer.
The Parameter data type is set to
Inherit:Inherit via internal rule.The value of the gain parameter can be represented without losing any precision by a built-in integer.
The Parameter minimum and Parameter maximum values in the Parameter Attributes tab of the Gain block parameters can be represented without losing any precision by a built-in integer.
Settings
Default: Off
On For Gain blocks with the Parameter data type set to
Inherit:Inherit via internal rule, the parameter data type compiles to a built-in integer type whenever possible.
OffFor Gain blocks with the Parameter data type set to
Inherit:Inherit via internal rule, the parameter data type is the type which maximizes precision.
Tips
This optimization affects both simulation and code generation.
This optimization affects only Gain blocks in the model.
For more efficient code, specify the Parameter minimum and Parameter maximum values in the Parameter Attributes tab of the Gain block parameters.
Dependencies
In cases where the data type of the gain parameter compiles to a fixed-point data type (non-zero scaling), the software checks out a Fixed-Point Designer™ license.
