numberformat, trunc and round

[jbv at souslelogo.com]

Hi list,

This might sound like a dumb question, but I'm scratching my head trying
to find a workaround.
I have this portion of script :
   set numberformat to "#.0000000"
   if myvar = trunc(myvar) then
     get myarray[myvar]
   end if

The problem seems to be that when numberformat is set, both trunc() and 
round()
keep the fractional part of myvar (2.000000); and since the indexes of 
myarray
are integers (1,2,3,etc), "get myarray[myvar]" always returns empty...
And I need to set numberformat to "#.0000000", because there are some 
rather
complex computations processed with the values in myarray inside a main 
loop.
And for various other reasons I can't use indexes with fractional part 
in the
array.
Of course, I could use :
   set numberformat to "#.0000000"
   set itemdelimiter to "."
   if myvar = trunc(myvar) then
     get myarray[item 1 of myvar]
   end if
But that's not very elegant and slows down the script a bit...
Any help would be much appreciated.

Best,
jbv
