1497	Sign(<expression>) function	jchd		"AutoIt lacks a Sign() function.

It would be a must if Sign could deal with close to 0 reals, i.e.:
  Sign($fp) = 0  iff  -$Epsilon <= $fp <= $Epsilon

When passed non-numeric variants, it could be made to return sensible results as well."	Feature Request	closed		AutoIt		None	Rejected	Sign
