WP 34S binomial bug?

[Paul Dale]

The upper functions are the probability that the distribution is greater than or equal to the given argument.

Binom returns the probability for less than or equal to the given value from X.
Binom_u returns the probability for greater than or equal to the given value from X.

For continuous distributions ABCD_u = 1 - ABCD, although they are not computed this way for accuracy reasons. For discrete distributions this relationship doesn't hold for integral arguments since the argument's probability is counted both ways.
