It doesn't really matter since the max precision is 15-20 digits anyway (I don't remember it exactly).

Just a guess: The max number of decimal places is 18. One is reserved for the decimal point. So, 256 - 18 - 1 = 237.

>As you know, STR(nVar,nWidth,nDec) returns a string from a numeric value. What you probably didn't know is that nWidth cannot exceed 237. Anyone know why? I could understand 254 maybe, but 237 seems arbitrary.
