Method Detail

makeNumber

ResultFormulaType makeNumber(long number)

makeNumber

ResultFormulaType makeNumber(BigInteger number)

makeNumber

ResultFormulaType makeNumber(double number)

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.

makeNumber

ResultFormulaType makeNumber(BigDecimal number)

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.

makeNumber

ResultFormulaType makeNumber(String pI)

makeNumber

ResultFormulaType makeNumber(Rational pRational)

makeVariable

ResultFormulaType makeVariable(String pVar)

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.

getFormulaType

FormulaType<ResultFormulaType> getFormulaType()

negate

ResultFormulaType negate(ParamFormulaType number)

add

ResultFormulaType add(ParamFormulaType number1,
                      ParamFormulaType number2)

sum

ResultFormulaType sum(List<ParamFormulaType> operands)

subtract

ResultFormulaType subtract(ParamFormulaType number1,
                           ParamFormulaType number2)

divide

ResultFormulaType divide(ParamFormulaType number1,
                         ParamFormulaType number2)

multiply

ResultFormulaType multiply(ParamFormulaType number1,
                           ParamFormulaType number2)

equal

BooleanFormula equal(ParamFormulaType number1,
                     ParamFormulaType number2)

distinct

BooleanFormula distinct(List<ParamFormulaType> pNumbers)

all given numbers are pairwise unequal.

greaterThan

BooleanFormula greaterThan(ParamFormulaType number1,
                           ParamFormulaType number2)

greaterOrEquals

BooleanFormula greaterOrEquals(ParamFormulaType number1,
                               ParamFormulaType number2)

lessThan

BooleanFormula lessThan(ParamFormulaType number1,
                        ParamFormulaType number2)

lessOrEquals

BooleanFormula lessOrEquals(ParamFormulaType number1,
                            ParamFormulaType number2)

floor

NumeralFormula.IntegerFormula floor(ParamFormulaType formula)

The floor operation returns the nearest integer formula that is less or equal to the given argument formula.

For rational formulae, SMTlib2 denotes this operation as to_int.
