How can I round down for the any number? 1

[nneverwaste]

I want to round down 0.369 to 0.3? (nominal precision = 1)
0.319 to 0.3
0.392 to 0.3

When you say you want to 'Round Down' numbers, are we talking about when placing dimensions on a Drawing or when working with numbers in the Expression system?

Hi,

a=0.369
b=floor(10*a)/10 ==> b=0.3

Dear JohnRBaker and DidierPSICAD

I am talking about placing dimensions on a Drawing.

You can't.

NX follows engineering best practices (which are supported by industry standards) for the rounding of Drafting dimensions so as to mitigate the effects of potential accumulated errors. What you're proposing would produce an unworkable long term situation.
