(AB<=BC) || (BCA==90) || (BAC>=90) verify in int and if No
1001 ways for approximating calculations after

PS: It is possible to make mistake about ==90
ABC==90 - May be! and it is test 26
Some time I was under influence of the fact that in
90-triangles for equality is enought 2 elements.

Also it is interesting that special cases should
verified under integer considerations all times
because numeric methods are bad near this cases due big error multiplicators.
