Sharp PC-G850 vs. G850VS

[AeeeO]

Hi all,

I've been on this forum quite some years ago, but don't remember my username anymore. So I registered anew!

I have both the Sharp PC-G850 and the G850VS. Main difference being the much better display on the VS and the auto line numbering in BASIC and C on the latter. TYPEDEF seems to not work on either machine, altough it is printed in the Japanese, the German and the English manual.

Now I discovered another difference and possibly a bug in the VS. I ran this tiny C code on both, after getting incorrect results on the VS from a more complicated formula that I couldn't explain:

10 main(){
20 double a,b,c;
30 scanf("%f",&a);
40 scanf("%f",&b);
50 c=pow(a,b);
60 printf("c=%f",c);
70 }

I entered a=10 and b=2.
The result on the G850 was c=100.000000 as expected.
The result on the G850VS was c=100.148079

Can this be a bug in the VS or am I missing something?

If it's a precision problem of the datatypes float, double, long double: why the difference in the two machines?

Regards,
Alexander
