problem with |MUL ?

Hi there.

I've been trying to convert an old program to CPC Basic 3, and I've come across what may be an error.

Code:

10 piHalf=0
20 con2=0:|VAL,con2,"1.0"
30 |PI,piHalf
40 |MUL,piHalf,piHalf,con2
50 |CINT,@tmp,piHalf
60 PRINT tmp


In the attached code, I'm expecting to see 3 printed on-screen, as PI*1=PI.
Instead, I am getting 10 being printed.
(I have Real Numbers set to 2 in the IDE).


When I change line 20 to:

Code:

20 con2=0:|VAL,con2,"2.0"


I am expecting it to print 6 to the screen, but it is still printing 10.


Am I doing something wrong, or is |MUL flawed?


When I change line 40 to:

Code:

40 |ADD,piHalf,piHalf,piHalf


I get 6 being printed, which is what I expect, as I am simply adding PI to itself

Please ignore this question.
I was indeed making a mistake - I wasn't setting the indexes for the REALs correctly.

Changing line 20 to:

Code:

20 con2=1:|VAL,con2,"1.0"


has fixed the problem.
