Rounded Mean help (to the tenth place)

[Jme (Jme Munn)]

I’d like to check for the Mean of aggregate data rounded to the nearest tenth place, but the function round(x) only produces a whole number integer.
How can I check for the rounded mean of aggregate data to the nearest tenth place in a graph?
(Thanks in advance!)

Could you “trick” it? Multiply by 10, round, then divide by ten?

As in:

a = input*10
b = round(a)
c = b/10

then your output is c

Rounding & Truncating

Searching the forum, I found a way to round a value to 2 decimal places (useful in CL documentation?) rounded_value = simpleFunction("\operatorname{round}(k,2)",“k”).evaluateAt(value) Using this I can also round to an integer by setting the number of decimal places to zero but is there a better way? Also, is there an operator for ‘truncate’? I tried that and ‘trunc’ in the above but no success.

Just pass the number of decimal places you want the number rounded to as another argument.

round(number,digits)

@Aethir

a = input*10
b = round(a)
c = b/10

Yeah! That totally worked! Thanks for the simple fix
I appreciate the help!

This way is even simpler!
I tried it second and way less steps.
I’m going with this way!
Thanks!
