Simp

-- Option variable: simp Default value: true

simp enables simplification. This is the standard. simp is also an evflag, which is recognized by the function ev. See ev.

When simp is used as an evflag with a value false, the simplification is suppressed only during the evaluation phase of an expression. The flag can not suppress the simplification which follows the evaluation phase.

Examples:

The simplification is switched off globally. The expression sin(1.0) is not simplified to its numerical value. The simp-flag switches the simplification on.

          (%i1) simp:false;
          (%o1)                                false
          (%i2) sin(1.0);
          (%o2)                              sin(1.0)
          (%i3) sin(1.0),simp;
          (%o3)                          .8414709848078965

The simplification is switched on again. The simp-flag cannot suppress the simplification completely. The output shows a simplified expression, but the variable x has an unsimplified expression as a value, because the assignment has occurred during the evaluation phase of the expression.

          (%i4) simp:true;
          (%o4)                                true
          (%i5) x:sin(1.0),simp:false;
          (%o5)                          .8414709848078965
          (%i6) :lisp $X
          ((%SIN) 1.0)

There are also some inexact matches for simp. Try ?? simp to see them.

(%o1)                                true
(%i2)
