Yes. Or, more precisely, a binary floating-point approximation of pi truncated to 48 bits (which is what reals in CAS are limited to), it's the closest CAS can get to pi, and the 'dec' program reveals exactly what that approximation is equal to.

If you understand the above, you can answer both of these questions:
(1) Why doesn't dec(0.1) return a "clean" decimal result?
(2) Why DOES dec(0.5) return a "clean" decimal result?
