The probability is too close to or . f is too far out into the tails for the probability to be evaluated exactly. The result tends to approach if is large, or if is small. The result returned is a good approximation to the required solution.

On entry, .
The result should be accurate to five significant digits.
8Parallelism and Performance
Background information to multithreading can be found in the Multithreading documentation.
g01edc is not threaded in any implementation.
For higher accuracy g01eec can be used along with the transformations given in Section 3.
This example reads values from, and degrees of freedom for, a number of -distributions and computes the associated lower tail probabilities.
