Hp50g emu : graph abs(x)^3 gives negative y-values

[Gil]

No, at least not in my EMU48 Android application :
two different behaviours, as mentioned, when
Rigorous mode is OFF ( -119 flag is set to 1).

Again, in other words :
-119 SF ENTER
-5 'X' STO

then
a) Graph will show point
(-5,-5) [a negative part of y=f(x)],
and not (-5,+5), but

b) ABS(X) ENTER EVALUATE
will give a positive number (+5).

Well, when -119 is set, I
would expect the same result in both cases a) and b).

Or did I miss something?
