Comment (by fujiwara):

 Current code does not catch floating underflow.
 I made trac2992 branch and pushed my fix.
  [2992] Added errno check to fromStringstreamNumber()
            Now support LONG_MAX, LONG_MIN and floating underflow detection
  [2992] Added integer conversion tests (LONG_MAX, -LONG_MAX, LONG_MIN)
            Added floating underflow test
 Does it make sense ?
