Rounding generally rounds to decimal places, so 10.5 is an odd rounding.  It's probably doable, but depends on exactly what precision you're looking for.

thanks for the link but my problem is: i can't find the correct syntax into the template about the variable Z (check my example above)

for example i'm using: round($tplvars['Z'],1) and nothing happens.....
