Returns the BFMSS separation bound.
Returns the BFMSS separation bound.
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.
Returns a bound on the degree of this expression.
Returns a bound on the degree of this expression.
A set of flags we can quickly compute for an Algebraic expression.
Returns the bound for zbf, using a cached value if it is available.
Returns the bound for zbf, using a cached value if it is available.
Returns the Li & Yap separation bound.
Returns the Li & Yap separation bound.
Returns a lower bound on the absolute value of this expression as a bit bound.
Returns a lower bound on the absolute value of this expression as a bit bound.

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.
Returns an integer with the same sign as this expression.
Returns an integer with the same sign as this expression.
Returns an asbolute approximation to this expression as a BigDecimal that is accurate up to +/- 10^-digits.
Returns an asbolute approximation to this expression as a BigDecimal that is accurate up to +/- 10^-digits.
Returns an upper bound on the absolute value of this expression as a bit bound.
