The classic procedure is:
1) multiply by 1000 2) add 0.5 3) truncate to an integer 4) divide by 1000
But step 4 may introduce an "error" because 1/1000 is not exactly expressible as a floating point binary number. Figuring out how to tell AppleScript to print in a three decimal digit format is beyond my mental capacity. Perhaps inserting the decimal point into the character string that represents the integer at step 3.
ah ha! ...
I think I'll use that til something goes wrong..
Thanks very much
