- acos() now returns 0 for a domain error.

- asin() now returns 0 for a domain error.

- atan2() now returns 0 for a domain error.

- fmod() now returns x if y == 0 and sets a
  domain error.

- sqrt() now returns 0 for a domain error.

- Added NaN and +Inf constants to the math library
  initialization code which could come in handy later.
