isboolean

Determine whether input is Boolean

Syntax

tf = isboolean(a)

tf = isboolean(T)

Description

tf = isboolean(a) returns 1 (true) when the DataType property of fi object a is Boolean. Otherwise, it returns 0 (false).

tf = isboolean(T) returns 1 (true) when the DataType property of numerictype object T is Boolean. Otherwise, it returns 0 (false).

Examples

Determine Whether fi Object is a Boolean

Create a fi object and determine if its data type is Boolean.

a = fi(pi)

a = 
    3.1416

          DataTypeMode: Fixed-point: binary point scaling
            Signedness: Signed
            WordLength: 16
        FractionLength: 13

tf = isboolean(a)

tf = logical
   0

a = fi(pi,'DataType','Boolean')

a = 
   1

          DataTypeMode: Boolean

tf = isboolean(a)

tf = logical
   1

Determine Whether numerictype Object is a Boolean

Create a numerictype object and determine if its data type is Boolean.

T = numerictype

T =


          DataTypeMode: Fixed-point: binary point scaling
            Signedness: Signed
            WordLength: 16
        FractionLength: 15

tf = isboolean(T)

tf = logical
   0

T = numerictype('Boolean')

T =


          DataTypeMode: Boolean

tf = isboolean(T)

tf = logical
   1
