Thank you for the hint with DOUBLE. This works for me too.

Betreff: Re: Ruta: order while execution of actions in rule?
Hi,
just a quick comment...
The actions are executed from left to right.
I tried to reproduce it (ruta 2.6.0). There seems to be a bug affecting the
FLOAT variable.
When I replace the line
FLOAT a2,a1;
with
DOUBLE a2,a1;
it seems to work.
I need to investigate it further in order to narrow down the cause.
Best,
Peter
