float

Create Simulink.NumericType object describing floating-point data type

Syntax

a = float('half')
a = float('single')
a = float('double')


Description

a = float('half') returns a Simulink.NumericType object that describes the data type of an IEEE^® half (16 total bits, 5 exponent bits).

a = float('single') returns a Simulink.NumericType object that describes the data type of an IEEE single (32 total bits, 8 exponent bits).

a = float('double') returns a Simulink.NumericType object that describes the data type of an IEEE double (64 total bits, 11 exponent bits).

Note

float is a legacy function. In new code, use fixdt instead. In existing code, replace float('half') with fixdt('half'), float('single') with fixdt('single'), and float('double') with fixdt('double').

Examples

Define an IEEE single data type.

>> a = float('single')

a = 

  NumericType with properties:

    DataTypeMode: 'Single'
         IsAlias: 0
       DataScope: 'Auto'
