template<class Base > bool CppAD::IdenticalZero ( const AD< Base > &  x ) Determine if an AD<Base> is equal to zero, and must be equal zero during any tape playback. Parameters: x object that we are checking. Returns: returns true if and only if x is equals zero and is identically a parameter IdenticalPar. Definition at line 107 of file identical.hpp.
