Method Summary

Modifier and Type	Method	Description
String	getExponent(boolean biased)	Return the exponent value of a floating-point numeral as a string Remarks: NaN is an invalid argument.
BitVecExpr	getExponentBV(boolean biased)	The exponent of a floating-point numeral as a bit-vector expression Remarks: NaN is an invalid argument.
long	getExponentInt64(boolean biased)	Return the exponent value of a floating-point numeral as a signed 64-bit integer Remarks: NaN is an invalid argument.
boolean	getSign()	Retrieves the sign of a floating-point literal Remarks: returns true if the numeral is negative
BitVecExpr	getSignBV()	The sign of a floating-point numeral as a bit-vector expression Remarks: NaN's do not have a bit-vector sign, so they are invalid arguments.
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.
BitVecExpr	getSignificandBV()	The significand of a floating-point numeral as a bit-vector expression Remarks: NaN is an invalid argument.
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.
boolean	isInf()	Indicates whether the numeral is a +oo or -oo.
boolean	isNaN()	Indicates whether the numeral is a NaN.
boolean	isNegative()	Indicates whether the numeral is negative.
boolean	isNormal()	Indicates whether the numeral is normal.
boolean	isPositive()	Indicates whether the numeral is positive.
boolean	isSubnormal()	Indicates whether the numeral is subnormal.
boolean	isZero()	Indicates whether the numeral is +zero or -zero.
String	toString()	Returns a string representation of the numeral.

Method Details

getSign

public boolean getSign()

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

Throws:

Z3Exception

getSignBV

public BitVecExpr getSignBV()
