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).

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

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.
