File non trovato.File non trovato.Hello
Happy new year for everyone.




I have detected a little problem (bug ?) about zero and the units .

example1:
v10=10m/s
v12=10m/s
dt=10ms
a11=(V12-V10)/dt=0 NO UNIT displayed


example2:
(see file joined):
a vector v with units m/s
an expression
Ec=1/2.m.v^2 gives a value
Ec=1/2.m.v gives a vector

Thanks a lot
Ph.D

Units don't match. Maths are unit-less. The units system sub-processes.
Best procedure is start/construct the project sterilized of units,
or match units at final.
