Definition at line 63 of file Scalar.hpp.

Scalar::Scalar	(	s4	constant,
		const NumericInstruction &	instruction
	)

inline

Creates a scalar which equals constant + instruction.

The expression must not over- or underflow!

void Scalar::lowerBoundOfMaximumWith ( const Scalar & other )

inline

Computes a lower bound of the maximum of this and the specified scalar.

The result is stored in this object.

Definition at line 140 of file Scalar.hpp.

void Scalar::lowerBoundOfMinimumWith ( const Scalar & other )

Computes a lower bound of the minimum of this and the specified scalar.

The result is stored in this object.

bool Scalar::tryAdd ( const Scalar & other )

Tries to add a scalar to this scalar.

If an overflow can happen or the result is not representable as a scalar, this scalar will not be changed and false will be returned. Otherwise the return value is true.

Definition at line 88 of file Scalar.cpp.

bool Scalar::trySubtract ( const Scalar & other )

Tries to subtract a scalar from this scalar.

If an overflow can happen or the result is not representable as a scalar, this scalar will not be changed and false will be returned. Otherwise the return value is true.

void Scalar::upperBoundOfMaximumWith ( const Scalar & other )

Computes an upper bound of the maximum of this and the specified scalar.

The result is stored in this object.

void Scalar::upperBoundOfMinimumWith ( const Scalar & other )

inline

Computes an upper bound of the minimum of this and the specified scalar.

The result is stored in this object.
