Get value from 2D array of decimal numbers

Get value from 2D array of decimal numbers

I am trying to determine if Zoho will work for our company.  The only issue I have found so far is whether we can get a specific value from a large two dimensional array of decimal numbers.
I have examined the list functions that apply nicely to one dimensional arrays and can imagine some possible ways to use these. My possible ways are very inelegant, however, and I suspect others have found some elegant ways to do this.
