Neat! I never realized that.
It works for the number just above pi, too; you just get the ten's complement of those extra digits:

Code:
10.00000000000E-10 -4.10206761537E-10 ------------------  5.89793238463E-10

I guess the point is that the calculator performs argument reduction using an extended-precision approximation of pi. Next question, for extra credit: how many digits?
