Description:

• An assignment autosimplify = activation value, where activation value is one of on or off, activates respectively deactivates the automatic safe simplification of expressions of functions generated by the evaluation of commands or in argument of other commands.
  
  Sollya commands like remez, taylor or rationalapprox sometimes produce expressions that can be simplified. Constant subexpressions can be evaluated to dyadic floating-point numbers, monomials with coefficients 0 can be eliminated. Further, expressions indicated by the user perform better in many commands when simplified before being passed in argument to a command. When the automatic simplification of expressions is activated, Sollya automatically performs a safe (not value changing) simplification process on such expressions.
  
  The automatic generation of subexpressions can be annoying, in particular if it takes too much time for not enough benefit. Further the user might want to inspect the structure of the expression tree returned by a command. In this case, the automatic simplification should be deactivated.
  
  If the assignment autosimplify = activation value is followed by an exclamation mark, no message indicating the new state is displayed. Otherwise the user is informed of the new state of the global mode by an indication.
