ROUNDDOWN or Ln (Help)

[Anonymous]

I have this problem that I hope someone can help me solve, I hope its simple...

What im trying to do is to make iLogic Rounddown the d51 (Pattern) by using Ln but it does not work. Any idea why? "See pictures"

Hi,

You can use the code snippets in the Math section.

Hmm. I think, you've been stumbling here:

There are two separate columns in the table above.

I ended up doing this since I could not make it work and I dont know why. But this Works. see pix.

The reason you could not make this work is that you were trying to use the Ln (natural logarithm) function to do what the Floor function was intended for.  As Walter illustrated, you were simply misreading the table of available iLogic math functions.

Glad you got it figured out,
