Not really.

There are many of those around.

Don't you mean the approximate value correct to 7 decimal places?

But when would you ever have the need to have that many decimals
in the value of z?

or, more accurately, .8915043004722... and I have a program on
my PC, named ET (Electronic Tables) that can calculate the tail
areas of most of the commonly used probability distributions
(normal, Student t, F chi-square, exponential, Weibull, lognormal,
noncenral chi-sq, gamma, beta, ...) up to 100 places of decimal
accuracy. But who needs it???
