issigned
Determine whether fi
object is signed
Syntax
Description
Examples
Determine Whether fi
Object Is Signed
Create a fi
object and determine whether it is signed or unsigned.
a1 = fi(pi,1)
a1 = 3.1416 DataTypeMode: Fixed-point: binary point scaling Signedness: Signed WordLength: 16 FractionLength: 13
tf = issigned(a1)
tf = logical
1
a2 = fi(pi,0)
a2 = 3.1416 DataTypeMode: Fixed-point: binary point scaling Signedness: Unsigned WordLength: 16 FractionLength: 14
tf = issigned(a2)
tf = logical
0
If a numerictype
object with Auto Signedness
is used to create a fi
object, the Signedness
property of the fi
object automatically defaults to Signed
.
T = numerictype('Signedness','Auto')
T = DataTypeMode: Fixed-point: binary point scaling Signedness: Auto WordLength: 16 FractionLength: 15
a3 = fi(pi,T)
a3 = 1.0000 DataTypeMode: Fixed-point: binary point scaling Signedness: Signed WordLength: 16 FractionLength: 15
tf = issigned(a3)
tf = logical
1
