bug in calcru()

[Chris Landauer]

hihi, doug -

thanx for the suggestion - the notion of computing ut just with subtraction is
really good, since it is likely to be the largest of the three values in most
applications, but i'm a little worried that the 1024 multiplications aren't
large enough when tt gets really large - i'll do the math on it and report its
(provable) range of applicability and accuracy in a few days

more soon,
cal
