For creating a heap image of isac see ~~/ROOT.

ATTENTION: no errors in this theory do not mean that there are no errors in Isac;

errors are rigorously detected when creating a heap.

text {* 

  In 2002 isac already strived for floating point numbers. Since that time

  isac represents numerals as "Free", see below (*1*). These experiments are

  unsatisfactory with respect to logical soundness.

  Since Isabelle now has started to care about floating point numbers, it is high 

  time to adopt these together with the other numerals. Isabelle2012/13's numerals

  are different from Isabelle2011, see "test/Tools/isac/ProgLang/termC.sml".

  The transition from "Free" to standard numerals is a task to be scheduled for 

  several weeks. The urgency of this task follows from the experience, 

  that (1.2) for "thehier" is very hard, because "num_str" seems to destroy 

  some of the long identifiers of theorems which would tremendously simplify

  building a hierarchy of theorems according to (1.2), see (*2*) below.
