Force increment step in parameter

Dimitris Kar

Hi,

 

I am trying to force the minimum increment in parameters that user defines.

 I managed to implement the min max to force the limits of my parameter (i.e. if 3<=x<=10, I write x=max(x 3)   x=min(x 10))

 I can not find the correct expresion on setting the acceptable step i.e. if the grid is 0.1, then values of x.xxx are not accepted.

 

An suggestions will be warmly welcomed!

 

Many thanks!

     OK, now you explained that you're talking about a CDF parameter and gave an example, your question is clear.

     Create a function such as this:

     procedure(CCFonGrid(param lower upper grid)
      let((value)
        value=get(cdfgData param)->value
        value=min(max(value lower) upper)
        get(cdfgData param)->value=round((value/float(grid)))*grid
      )
    )

    And then in your cdfCreateParam call, pass:

      ?callback "CCFonGrid('x 3 10 0.05)"

    Note that in the code you showed, r= 10**-log10(grid) is a complicated way of saying r=1/grid. If you rearrange the expression a little, there's no need to find the reciprocal anyway.

    I've written the above callback code to use get() and to pass the parameter name in, because that way you can use it for multiple CDF parameters with different lower and upper limits and different grids.

    Regards,

    Andrew.
