Support: floating-point numbers

R2026b

Code generation for floating-point data

Model Configuration Pane: Code Generation / Interface

Description

The Support: floating-point numbers parameter specifies whether to generate code for floating-point data and operations on floating-point data.

• The setting of this parameter must be the same for the models in a model hierarchy.

• Selecting this parameter enables the Support: non-finite numbers parameter and clearing this parameter disables Support: non-finite numbers.

• If you select the MAT-file logging parameter, select this parameter and the Support: non-finite numbers parameter.

Settings

On (default) | Off

On

Enables generation of floating-point data and related operations.

Off

Disables generation of floating-point data and operations. Code generator produces pure integer code. If you clear this parameter and the code generator encounters floating-point data or expressions, an error occurs. The error message reports offending blocks and parameters.

Recommended Settings

Application	Setting
Debugging	No impact
Traceability	No impact
Efficiency	Off — for integer only

Programmatic Use

Parameter: SupportFloatingPoint

Type: character vector

Value: 'on' | 'off'

Default: 'on'

Version History

Introduced before R2006a

R2026b: SupportFloatingPoint replaces PurelyIntegerCode

The programmatic name PurelyIntegerCode is now SupportFloatingPoint and its programmatic settings match the settings of the dialog box. Setting SupportFloatingPoint to 'on' corresponds to setting Support: floating-point numbers to "On" in the dialog box.

There are no plans to remove support for references to PurelyIntegerCode. Its settings remain the same.
