Method Detail

makeNumber

public ResultFormulaType makeNumber(long number)

Specified by:

makeNumber in interface NumeralFormulaManager<ParamFormulaType extends NumeralFormula,ResultFormulaType extends NumeralFormula>

makeNumber

public ResultFormulaType makeNumber(BigInteger number)

Specified by:

makeNumber in interface NumeralFormulaManager<ParamFormulaType extends NumeralFormula,ResultFormulaType extends NumeralFormula>

makeNumber

public ResultFormulaType makeNumber(double number)

Description copied from interface: NumeralFormulaManager

Create a numeric literal with a given value. Note: if the theory represented by this instance cannot handle rational numbers, the value may get rounded or otherwise represented imprecisely.

Specified by:

makeNumber in interface NumeralFormulaManager<ParamFormulaType extends NumeralFormula,ResultFormulaType extends NumeralFormula>

makeNumber

public ResultFormulaType makeNumber(BigDecimal number)

Description copied from interface: NumeralFormulaManager

Create a numeric literal with a given value. Note: if the theory represented by this instance cannot handle rational numbers, the value may get rounded or otherwise represented imprecisely.

Specified by:

makeNumber in interface NumeralFormulaManager<ParamFormulaType extends NumeralFormula,ResultFormulaType extends NumeralFormula>

makeNumber

public ResultFormulaType makeNumber(String pI)

Specified by:

makeNumber in interface NumeralFormulaManager<ParamFormulaType extends NumeralFormula,ResultFormulaType extends NumeralFormula>

makeNumber

public ResultFormulaType makeNumber(Rational pRational)

Specified by:

makeNumber in interface NumeralFormulaManager<ParamFormulaType extends NumeralFormula,ResultFormulaType extends NumeralFormula>

makeVariable

public ResultFormulaType makeVariable(String pVar)

Description copied from interface: NumeralFormulaManager

Creates a variable with exactly the given name.

Please make sure that the given name is valid in SMT-LIB2. Take a look at FormulaManager.isValidName(java.lang.String) for further information.

This method does not quote or unquote the given name, but uses the plain name "AS IS". Formula.toString() can return a different String than the given one.

Specified by:

makeVariable in interface NumeralFormulaManager<ParamFormulaType extends NumeralFormula,ResultFormulaType extends NumeralFormula>

getFormulaType

public FormulaType<ResultFormulaType> getFormulaType()

Specified by:

getFormulaType in interface NumeralFormulaManager<ParamFormulaType extends NumeralFormula,ResultFormulaType extends NumeralFormula>

negate

public ResultFormulaType negate(ParamFormulaType number)

Specified by:

negate in interface NumeralFormulaManager<ParamFormulaType extends NumeralFormula,ResultFormulaType extends NumeralFormula>

add

public ResultFormulaType add(ParamFormulaType number1,
                             ParamFormulaType number2)

Specified by:

sum

public ResultFormulaType sum(List<ParamFormulaType> operands)

Specified by:

sum in interface NumeralFormulaManager<ParamFormulaType extends NumeralFormula,ResultFormulaType extends NumeralFormula>

subtract

public ResultFormulaType subtract(ParamFormulaType number1,
                                  ParamFormulaType number2)

divide

public ResultFormulaType divide(ParamFormulaType numerator,
                                ParamFormulaType denominator)

Description copied from interface: NumeralFormulaManager

Create a formula representing the division of two operands according to Boute's Euclidean definition (DOI: 10.1145/128861.128862).

If the denominator evaluates to zero (division-by-zero), either directly as value or indirectly via an additional constraint, then the solver is allowed to choose an arbitrary value for the result of the division (cf. SMTLib standard version 2.6 for the division operator in Int or Real theory). The details of this are implementation specific and may change solver by solver.

Note: Some solvers, e.g., Yices2, abort with an exception when exploring a division-by-zero during the SAT-check. This is not compliant to the SMTLIB standard, but sadly happens.

Specified by:

divide in interface NumeralFormulaManager<ParamFormulaType extends NumeralFormula,ResultFormulaType extends NumeralFormula>

multiply

public ResultFormulaType multiply(ParamFormulaType number1,
                                  ParamFormulaType number2)
