Methods

Modifier and Type	Method and Description
java.lang.String	getExponent() Return the exponent value of a floating-point numeral as a string
long	getExponentInt64() Return the exponent value of a floating-point numeral as a signed 64-bit integer
boolean	getSign() Retrieves the sign of a floating-point literal Remarks: returns true if the numeral is negative
java.lang.String	getSignificand() The significand value of a floating-point numeral as a string Remarks: The significand s is always 0 < s < 2.0; the resulting string is long enough to represent the real significand precisely.
long	getSignificandUInt64() The significand value of a floating-point numeral as a UInt64 Remarks: This function extracts the significand bits, without the hidden bit or normalization.
java.lang.String	toString() Returns a string representation of the numeral.

Method Detail

getSign

public boolean getSign()

Retrieves the sign of a floating-point literal Remarks: returns true if the numeral is negative

Throws:

Z3Exception

getSignificand

public java.lang.String getSignificand()

The significand value of a floating-point numeral as a string Remarks: The significand s is always 0 < s < 2.0; the resulting string is long enough to represent the real significand precisely.

Throws:

Z3Exception

getSignificandUInt64

public long getSignificandUInt64()

The significand value of a floating-point numeral as a UInt64 Remarks: This function extracts the significand bits, without the hidden bit or normalization. Throws an exception if the significand does not fit into a UInt64.

Throws:

Z3Exception

getExponent

public java.lang.String getExponent()

Return the exponent value of a floating-point numeral as a string

Throws:

Z3Exception

getExponentInt64

public long getExponentInt64()

Return the exponent value of a floating-point numeral as a signed 64-bit integer

Throws:

Z3Exception

toString

public java.lang.String toString()

Returns a string representation of the numeral.

Overrides:

toString in class Expr
