isslopebiasscaled

Determine whether numerictype object has nontrivial slope and bias scaling

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.
