In the FLOAT/DOUBLE to string conversions a class global string was used to store the result. Unfortunately it is possible for an instance of this class to be used by multiple threads of PrimProc simultaneously. This would cause a race and data corruption or more likely a crash. This fix passes a string object from the caller to use instead.
