Method Detail

toUpper

public RatNum toUpper(int precision)

Return a upper bound for a given real algebraic number. The interval isolating the number is smaller than 1/10^precision.

Parameters:

precision - the precision of the result

Returns:

A numeral Expr of sort Real

Throws:

Z3Exception - on error

See Also:

Expr#isAlgebraicNumber

toLower

public RatNum toLower(int precision)

Return a lower bound for the given real algebraic number. The interval isolating the number is smaller than 1/10^precision.

Parameters:

precision - precision

Returns:

A numeral Expr of sort Real

Throws:

Z3Exception - on error

See Also:

Expr#isAlgebraicNumber

toDecimal

public java.lang.String toDecimal(int precision)

Returns a string representation in decimal notation. Remarks: The result has at most precision decimal places.

Parameters:

precision - precision

Returns:

String

Throws:

Z3Exception - on error
