-There is a four position stack as in HP RPN calculators, labeled x, y, z, t from bottom to top. Trigonometric functions act on x, and algebraic functions act on y and x. It should be familiar to users of RPN calculators.

Entering pi loads the constant pi into x.
There are also exponentiation and logarithmic functions.
-Enter r to roll, which drops the stack and puts x into t.
