Unexpected Behavior of floor function

nicholas_aarestad

I've been experimenting with using the floor and ceiling functions for various instance counts, and there's one behavior that's got me scratching my head.

I have a configuration variable called #length.

When I use this in a Pattern Feature feature, I use this like floor(#length/in)

For most values, this works fine--  except that for integers, the value is 1 less than the actual value.

For example for #length = 24 in, the function returns 23. ceil() seems to be unaffected.

If I just directly input the value as 24, I get the expected floor(24)=24.

Is there something weird going on here with the unit division?

Apologies if this has already been asked about, but I couldn't find anything in the documentation or previous threads about this.

It is due to rounding in measurements with units
Can you try using floor(#length/in+TOLERANCE.zeroLength) instead

Thanks!

Did that work?

nicholas_aarestad

Yup. Worked like a charm-- do you know if this is documented anywhere?

I'm not sure.
Maybe @lougallo would know
