"c:\windows\data application\ttcalc\" now
changed: the program uses the TTMath 0.8.1 now
added:   from TTMath 0.8.1:
         root(x, index), bitand(x,y), bitor(x,y), bitxor(x,y)
         /band(x,y), bor(x,y), bxor(x,y)/
         asinh(x), acosh(x), atanh(x), acoth(x) /atgh(x), actgh(x)/
changed: from TTMath 0.8.1: calculations are much faster now
         especially the factorial() function
changed: from TTMath 0.8.1: the way of parsing operators
