For values of x around $$\pi$$, $$sin(x) \approx \pi-x$$

The value of $$\pi$$ is closer to 3.14159265358979, and $$3.14159265358979-3.141592654=-4.1021\times10^{-10}$$ so I'd say this machine is right on the money.

The inaccuracy here isn't in the calculator, it's in the assumed value of $$\pi$$.

I was not assuming anything...I was asking for the SIN of a specific input, and the HPs give a much higher accuracy than the TIZs...The HP 28, 42S, 48 series 50G and prime etc give the answer correct to 12 digits, the TI is not even close.
