round( ) function

Is it possible to specify the number of decimal places that the round( ) function rounds to? The standard Excel format of round(number, dp) doesn't seem to work. Alternatively, is there a workaround?. Thanks!

    round(value * 100) / 100 should do the trick (to 2 dp)

    round() as now a value and a multiple.

    @patrick_farley

    round(value, .01) is probably what you are looking for rather than round(value, 2):

    You'll notice also in that documentation that value and multiple can also both be valueWithUnits, and the result will come out as a plain number (whose "unit" corresponds to the "multiple")

    I'm trying to use the solution above, but I keep getting errors (Function Round with 2 argument(s) not found). Any idea what can go wrong here?

    Part of my code
    var es = definition["segment" ~ i] / millimeter;
    partNumber ~= toString(round(es, .01));

    @leon_tulling You're likely on a very old version of the FS standard library. The two-argument function was introduced around six years ago.

    @leon_tulling roundToPrecision() is the new way to do this. See here https://cad.onshape.com/FsDoc/library.html
