isslopebiasscaled

Determine whether numerictype object has nontrivial slope and bias scaling

Description

example

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
