All Implemented Interfaces:

FloatingPointFormulaManager

public abstract class AbstractFloatingPointFormulaManager<TFormulaInfo,TType,TEnv,TFuncDecl>
extends Object
implements FloatingPointFormulaManager

Similar to the other Abstract*FormulaManager classes in this package, this class serves as a helper for implementing FloatingPointFormulaManager. It handles all the unwrapping and wrapping from and to the Formula instances, such that the concrete class needs to handle only its own internal types.

For multiply(FloatingPointFormula, FloatingPointFormula), and divide(FloatingPointFormula, FloatingPointFormula) this class even offers an implementation based on UFs. Sub-classes are supposed to override them if they can implement these operations more precisely (for example multiplication with constants should be supported by all solvers and implemented by all sub-classes).

Description copied from interface: FloatingPointFormulaManager

Build a formula of compatible type from a FloatingPointFormula. This method uses the default rounding mode.

Compatible formula types are all numeral types and (signed/unsigned) bitvector types. It is also possible to cast a floating-point number into another floating-point type. We do not support casting from boolean or array types. We try to keep an exact representation, however fall back to rounding if needed.

Specified by:

castTo in interface FloatingPointFormulaManager

Parameters:

pNumber - the source formula of floating-point type

pSigned - if a BitvectorFormula is given as target, we additionally use this flag. Otherwise, we ignore it.

pTargetType - the type of the resulting formula

Description copied from interface: FloatingPointFormulaManager

Create a formula that interprets the given bitvector as a floating-point value in the IEEE format, according to the given type. The sum of the sizes of exponent and mantissa of the target type plus 1 (for the sign bit) needs to be equal to the size of the bitvector.

Note: This method will return a value that is (numerically) far away from the original value. This method is completely different from FloatingPointFormulaManager.castFrom(org.sosy_lab.java_smt.api.Formula, boolean, org.sosy_lab.java_smt.api.FormulaType.FloatingPointType), which will produce a floating-point value close to the numeral value.

remainder: x - y * n, where n in Z is nearest to x/y. The result can be negative even for two positive arguments, e.g. "rem(5, 4) == 1" and "rem(5, 6) == -1", as opposed to integer modulo operators.

Description copied from interface: FloatingPointFormulaManager

Create a term for comparing the equality of two floating-point terms, according to standard floating-point semantics (i.e., NaN != NaN). Be careful to not use this method when you really need FloatingPointFormulaManager.assignment(FloatingPointFormula, FloatingPointFormula).
