Hi Markus,

this patch removes the check for the upper bound of the second parameter of
TINV. I checked the algorithm of TINV but there seems to be no reason to
limit this number.

The only problem is that for values greater than 1E14 the rounding error
dramatically increases but in my opinion everyone who uses such large
numbers should know about problems related to rounding and floating point
arithmetic.

People tend to use and trust such functions anyway..
Does Excel impose some upper bound on that parameter? If so, we should
compare its output near such value with Calc's, and if sufficiently
"equal" maybe raise the bound. Another approach would be to compare with
Mathematica, Regina is known to love such work ;-)
