    Method used in preparation of splitting a string containing a numeric value with a metric unit (e.g. 18px, 9pt, 6cm, etc).
    
    Determines the position between digits and affiliated characters ('+','-','0-9' and '.') and all other characters.
    e.g. string "16px" will return 2, string "0.5em" will return 3 and string '-8.5mm' will return 4.
    
    Parameters:
    
    string - containing a numeric value with a metric unit
    
    Returns:
