formatting help

[coolmel55]

Need a bit of help formatting my output. I'm not even sure that this can be done. The output from the following code looks like this:

Here is your output!
********************
rval = 0.954316
tval = 9.03351
p = 0.999997
Two tailed value = 5.716140e-006

Ok is there anyway I can make the Two tailed value output look like this:
Two tailed value = 1.80 * 10^-5 (you know ^ -5 is the exponential)
