Hp50 'Integral (0,infinity,SIN(X)/X,X)' gives 5.04540304996

[Martin Hepperle]

... indeed, on the real 50g hardware I also obtained 5.04540304996 for the range 0...2*pi after about 30 minutes. So the simulator is "correct".

The HP 49G says 1.55488887105 for the same range.

Maple:
0...2*pi -> 1.418151576
2*pi ... oo -> 0.152644751

It is "funny" that the error seems to come from the higher x-values, where the function behaves better than around x=0.

Nice to see, that the Prime has the Si(x) integral in its CAS rules.
