Dear EM,

❝ Simple: Spreadsheet is the option and that's not my decision.

Some ways to overcome the limitations of the spreadsheet implementations of the t-distribution:

Use Excel and the VB code for the non-central t-distribution contained in Dave Dubbins Fartssie.xls. According to the comments within it, it should be able to handle fractional df's.
Use RExcel, an add-in for Excel on MS Windows, that allows to transfer data between R and Excel, writing VBA macros using R as a library for Excel, and calling R functions.
If MS Excel is not an option but OO Calc use "R and Calc", an OpenOffice.org (OO.o) Calc add-on that allows you to use R methods and functions.

To be honest, I have no experience with any of these suggestions.

BTW: The EXCEL built in function tinv also truncates fractional degrees of freedom.
