Create an integer from the bit-vector argument t .

NB. This function is essentially treated as uninterpreted. So you cannot expect Z3 to precisely reflect the semantics of this function when solving constraints with this function.

The argument must be of bit-vector sort.

Quantifier MkForall ( Sort[]  sorts, Symbol[]  names, Expr  body, uint  weight = 1, Pattern[]  patterns = null, Expr[]  noPatterns = null, Symbol  quantifierID = null, Symbol  skolemID = null  )

Create a universal Quantifier.

Creates a forall formula, where weight is the weight, patterns is an array of patterns, sorts is an array with the sorts of the bound variables, names is an array with the 'names' of the bound variables, and body is the body of the quantifier. Quantifiers are associated with weights indicating the importance of using the quantifier during instantiation. Note that the bound variables are de-Bruijn indices created using MkBound. Z3 applies the convention that the last element in names and sorts refers to the variable with index 0, the second to last element of names and sorts refers to the variable with index 1, etc.

Parameters

sorts	the sorts of the bound variables.
names	names of the bound variables
body	the body of the quantifier.
weight	quantifiers are associated with weights indicating the importance of using the quantifier during instantiation. By default, pass the weight 0.
patterns	array containing the patterns created using MkPattern.
noPatterns	array containing the anti-patterns created using MkPattern.
quantifierID	optional symbol to track quantifier.
skolemID	optional symbol to track skolem constants.

Selects the format used for pretty-printing expressions.

The default mode for pretty printing expressions is to produce SMT-LIB style output where common subexpressions are printed at each occurrence. The mode is called Z3_PRINT_SMTLIB_FULL. To print shared common subexpressions only once, use the Z3_PRINT_LOW_LEVEL mode. To print in way that conforms to SMT-LIB standards and uses let expressions to share common sub-expressions use Z3_PRINT_SMTLIB_COMPLIANT.
