```> both solutions are the same

well, not quite ;-) the first one will give you a number, the second will give you a symbol.

Gents,

both solutions are the same and the same perfectly works.
Thanks, no more newbie questions, just expressions.
Best,

*input* -> [* 100] -> [expr round(\$f1)] -> [* 0.01] -> *output*

if you just want to limit the precision for printing purposes, you can do:

*input* -> [makefilename %.2f] -> *output*

Dear list,
how can one limit the amount of digits of the decimal fraction in the number object?
To have instead of 33.3333 only 2 digits after the colon 33.33.

Sorry for the newbie Q,
