* Added in Excel 2010.
* The t distribution is a continuous distribution.
* This function only returns the left tail of the distribution.
* If "probability" <= 0, then #NUM! is returned.
* If "probability" > 1, then #NUM! is returned.
* If "probability" is not numeric, then #VALUE! is returned
* If "degrees_freedom" < 1, then #NUM! is returned.
* If "degrees_freedom" is not an integer then it is truncated.
* If "degrees_freedom" is not numeric, then #VALUE! is returned.
