# fixdt

Create `Simulink.NumericType`

object describing a fixed-point or
floating-point data type

## Syntax

## Description

returns a `a`

= fixdt(`Signed`

,`WordLength`

)`Simulink.NumericType`

object that describes a fixed-point data
type with the specified signedness and word length, and unspecified scaling.

returns a `a`

= fixdt(`Signed`

,`WordLength`

,`FractionLength`

)`Simulink.NumericType`

object that describes a fixed-point data
type with binary point scaling.

returns a `a`

= fixdt(`Signed`

,`WordLength`

,`TotalSlope`

,`Bias`

)`Simulink.NumericType`

object that describes a fixed-point data
type with slope and bias scaling.

returns a `a`

= fixdt(`Signed`

,`WordLength`

,`SlopeAdjustmentFactor`

,`FixedExponent`

,`Bias`

)`Simulink.NumericType`

object that describes a fixed-point data
type with slope and bias scaling.

returns a `a`

= fixdt(`DataTypeNameString`

)`Simulink.NumericType`

object that describes an integer,
fixed-point, or floating-point data type specified by the name of a data type.

returns a `a`

= fixdt(___,'DataTypeOverride','Off')`Simulink.NumericType`

object with its
`DataTypeOverride`

parameter set to `Off`

. The default
value for this property is `Inherit`

. You can specify the
`DataTypeOverride`

parameter after any combination of other input
parameters.

`[`

returns a `a`

,`IsScaledDouble`

] = fixdt(___)`Simulink.NumericType`

object that describes a fixed-point or
floating-point data type and a flag that indicates whether the specified data type is of a
scaled double data type.
