How can I round the length of each line

ciscolara · October 18, 2018, 10:57pm

Hello guys thanks for your help.
I need to round the lenght of each line to the nearest 0.05

For example if I have this value 0.464326 (which its the lenght of the line) and how can I convert it to 0.45 lenght?
I have a whole bunch of lines that I created but I need to round them all. I am attaching the def and the rhino

I do not need to round the text panel, but I need to round the lenght of each line.
The lines are created by 2 sets of points I might need to modify the position of this points?

Thanks again for your help.

I don’t do Grasshopper but in my Python code I’d use:

value = 0.05*round(value/0.05)

Regards,
Terry.

Perhaps you meant 0.446325 to 0.45 - that would be rounding and not reducing the length. You’ll have to use x = round(x,2)

if you have to 0.464325 to 0.45 - that is change of the value x = 0.45

if you want to cut the length of the of the value without rounding it has to be x = float(str(str(x)[:-4]))

If interested Pufferfish has a bunch of Rounding components, and if you wanted the lower end of the rounding like you say 0.464326 to 0.45 you can use the T input of the rounding components and set them to Floor.
