2011-01-12 wenzelm 2011-01-12 eliminated global prems; tuned proofs;
2010-12-06 hoelzl 2010-12-06 move coercions to appropriate places
2010-09-06 hoelzl 2010-09-06 When comparing Floats use integers instead of reals (represented as rationals), generates less code when Floats are used.
2010-05-09 huffman 2010-05-09 avoid using real-specific versions of generic lemmas
2010-02-23 huffman 2010-02-23 moved some lemmas from RealPow to RealDef; changed orientation of real_of_int_power
2010-02-08 haftmann 2010-02-08 separate library theory for type classes combining lattices with various algebraic structures
2009-11-10 wenzelm 2009-11-10 eliminated some old uses of cumulative prems (!) in proof methods;
2009-10-17 wenzelm 2009-10-17 eliminated hard tabulators, guessing at each author's individual tab-width; tuned headers;
2009-07-14 haftmann 2009-07-14 prefer code_inline over code_unfold; use code_unfold_post where appropriate
2009-07-14 haftmann 2009-07-14 code attributes use common underscore convention
2009-06-29 hoelzl 2009-06-29 Implemented taylor series expansion for approximation
2009-06-04 hoelzl 2009-06-04 Approximation: Implemented argument reduction for cosine. Sinus is now implemented in terms of cosine. Sqrt computes on the entire real numbers
2009-04-29 hoelzl 2009-04-29 replaced Ifloat => real_of_float and real, renamed ApproxEq => inequality, uneq => interpret_inequality, uneq' => approx_inequality, Ifloatarith => interpret_floatarith
2009-04-29 haftmann 2009-04-29 farewell to class recpower
2009-04-22 haftmann 2009-04-22 power operation defined generic
2009-03-04 blanchet 2009-03-04 Merge.
2009-03-04 blanchet 2009-03-04 Merge.
2009-03-01 nipkow 2009-03-01 removed redundant lemmas
2009-02-26 wenzelm 2009-02-26 standard headers; eliminated non-ASCII chars, which are fragile in the age of unicode;
2009-02-21 nipkow 2009-02-21 removed redundant thms
2009-02-18 huffman 2009-02-18 add header
2009-02-05 hoelzl 2009-02-05 Added new Float theory and moved old Library/Float.thy to ComputeFloat
2009-01-28 nipkow 2009-01-28 Replaced group_ and ring_simps by algebra_simps; removed compare_rls - use algebra_simps now
2008-12-09 huffman 2008-12-09 move all neg-related lemmas to NatBin; make type of neg specific to int
2008-12-03 huffman 2008-12-03 enable eq_bin_simps for simplifying equalities on numerals
2008-12-03 huffman 2008-12-03 fix proofs related to simplification of inequalities on numerals
2008-12-03 haftmann 2008-12-03 made repository layout more coherent with logical distribution structure; stripped some $Id$s
