  6. def children: List[Expr]

    Returns a list of the children of this expression.

    Returns a list of the children of this expression. A child is a sub-expression required by this expression. For instance, Add has 2 children, the left-hand and right-hand side sub-expressions. A numeric literal expression, such as ConstantDouble or ConstantRational has no children.

  22. def separationBound: BitBound

    Returns a separation bound for this expression as a bit bound.

    Returns a separation bound for this expression as a bit bound. A separation bound is a lower-bound on the value of this expression that is only valid if this expression is not 0. This bound can thus be used to determine if this value is actually 0 and, if not, the sign, by simply approximating the expression with enough accuracy that it falls on one side or the other of the separation bound.
