Argument Description
value The value at which you want to evaluate the distribution and must not be negative.
degrees_freedom A positive integer stating the number of degrees of freedom.
tails Must be either 1 (one-tailed distribution) or 2 (two-tailed distribution).

This function is related to the TINV function in the following way:
If prob = TDIST(value, df ,2), then TINV(prob, df) = value
