Syntax

tf = isslopebiasscaled(T)

Description

tf = isslopebiasscaled(T) returns 1 (true) when numerictype T has nontrivial slope and bias scaling. Otherwise, it returns 0 (false). Slope and bias scaling is trivial when the slope is an integer power of two and the bias is zero.

Create a numerictype object and determine whether it has nontrivial slope and bias scaling.

T1 = numerictype
T1 =


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

tf = isslopebiasscaled(T1)
tf = logical
   0


T2 = numerictype('DataTypeMode',...
    'Fixed-point: slope and bias scaling',...
    'WordLength',32,...
    'Slope',2^-2,...
    'Bias',4)
T2 =


          DataTypeMode: Fixed-point: slope and bias scaling
            Signedness: Signed
            WordLength: 32
                 Slope: 0.25
                  Bias: 4

tf = isslopebiasscaled(T2)
tf = logical
   1


T3 = numerictype('DataTypeMode',...
    'Fixed-point: slope and bias scaling',...
    'WordLength',32,...
    'Slope',2^2,...
    'Bias',0)
T3 =


          DataTypeMode: Fixed-point: slope and bias scaling
            Signedness: Signed
            WordLength: 32
                 Slope: 2^2
                  Bias: 0

tf = isslopebiasscaled(T3)
tf = logical
   0
