Hi Chris,

if you want to round to whole numbers, just reroute your numbers through an Integer parameter. If you want to round to a specific number of decimal places, then you'll need to use an Expression. Either insert an Expression component or add an Expression to any number parameter.

If your number parameter is called "Num", then the expression should be: Round(Num, 3) in order to round to 3 decimal places.

Hi,
I need to round off to 5 (15, 20, 25, etc.). I have many results and I fixed Min and Max value and the parameter Integer at the end, but I need also numbers running in step of 5. Which expression I need to use?

thanks

Divide by 5 pass through an Integer Param and then Multiply by 5

I thought this might make a useful GH_User component so here is. It includes Floor and Ceiling functionality like the existing Rounding component.

Just drag the file on to the canvas and GH will do the rest.

How do you get grasshopper to ROUNDUP or ROUNDDOWN.... this works in other software such as Revit but I can't seem to find the correct code (or maybe it doesn't exist)

thanks

There is a Round component in the Maths Tab > Utility Panel which has three outputs

N = normal, 4.3 --> 4 & 4.6 --> 5

F = Floor, 4.3 --> 4 & 4.6 --> 4

C = Ceiling, 4.3 --> 5 & 4.6 --> 5
