Bug or Not? Taking STRING of a string whilst making leading zeros

[Joe Horn]

Warning #1: The output of STRING(X) depends on the current Number Format in Home Settings. For example, STRING(456) in Fixed 2 mode returns "456.00" which might not be what you want. To insure that whole numbers always get turned into strings without decimal places, use the optional second argument to specify the desired format regardless of the current setting. STRING(456,1) --> "456" (the 1 here means "use Standard number format").

Warning #2: In CAS programs, be sure to use the newer, smarter function STRING(), not its older, dumber sibling string(). Thankfully, Home always uses STRING().
