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:

Parameters:

source - the source formula of floating-point type

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

targetType - 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.
