Member Function Documentation

◆ Add()

bool ON_ArithmeticCalculator::Add ( )

Description: Enter an explicit addition operator whose operands are the previous value and the next value, where a value is a number, simple number, or parenthetic expression.

◆ ClearAll()

void ON_ArithmeticCalculator::ClearAll ( )

Description: Clear all status, values and expressions.

◆ Divide()

bool ON_ArithmeticCalculator::Divide ( )

Description: Enter an explicit division operator whose operands are the previous value and the next value, where a value is a number, simple number, or parenthetic expression. If the second value is zero, the calculator state is set to error.

◆ ErrorCondition()

ERROR_CONDITION ON_ArithmeticCalculator::ErrorCondition ( ) const

◆ Evaluate()

bool ON_ArithmeticCalculator::Evaluate ( double * value )

Description: Calculate the current value.

◆ ImpliedMultiplication()

bool ON_ArithmeticCalculator::ImpliedMultiplication ( ) const

Configuration Settings

◆ LeftParenthesis()

bool ON_ArithmeticCalculator::LeftParenthesis ( )

Description: Begin a parenthetic expression.

◆ Multiply()

bool ON_ArithmeticCalculator::Multiply ( )

Description: Enter an explicit multiplication operator whose operands are the previous value and the next value, where a value is a number, simple number, or parenthetic expression.

◆ Number()

bool ON_ArithmeticCalculator::Number ( double x )

Calculator keys Description: Enter a number that can be used as an implied multiplication operand when implied multiplication is enabled and appropriate.

◆ operator=() [1/2]

ON_ArithmeticCalculator& ON_ArithmeticCalculator::operator= ( const ON_ArithmeticCalculator & )

◆ operator=() [2/2]

ON_ArithmeticCalculator& ON_ArithmeticCalculator::operator= ( ON_ArithmeticCalculator && )

◆ ParenthesesDepth()

unsigned int ON_ArithmeticCalculator::ParenthesesDepth ( ) const

Returns: The current number of parenthetic expressions that are not completed.

◆ PendingImpliedMultiplication()

bool ON_ArithmeticCalculator::PendingImpliedMultiplication ( ) const

Returns: True if an implied multiplication will be applied to the next number or parenthetical expression.

◆ PendingUnaryMinus()

bool ON_ArithmeticCalculator::PendingUnaryMinus ( ) const

Returns: True if a unary minus is pending and will be applied to the next number or parenthetical expression.

◆ PendingUnaryOperation()

bool ON_ArithmeticCalculator::PendingUnaryOperation ( ) const

Returns: True if a unary plus or unary minus is pending

◆ PendingUnaryPlus()

bool ON_ArithmeticCalculator::PendingUnaryPlus ( ) const

Returns: True if a unary plus is pending and will be applied to the next number or parenthetical expression.

◆ RightParenthesis()

bool ON_ArithmeticCalculator::RightParenthesis ( )

Description: End a parenthetic expression.

◆ SetImpliedMultiplication()

void ON_ArithmeticCalculator::SetImpliedMultiplication ( bool bEnable )

◆ SimpleNumber()

bool ON_ArithmeticCalculator::SimpleNumber ( double x )

Description: Enter a number that will never use implied multiplication.

◆ Subtract()

bool ON_ArithmeticCalculator::Subtract ( )

Description: Enter an explicit subtraction operator whose operands are the previous value and the next value, where a value is a number, simple number, or parenthetic expression.

◆ UnaryMinus()

bool ON_ArithmeticCalculator::UnaryMinus ( )

Description: Enter an unary minus operator whose operand is the next number, simple number, or parenthetic expression.

◆ UnaryPlus()

bool ON_ArithmeticCalculator::UnaryPlus ( )

Description: Enter an unary plus operator whose operand is the next number, simple number, or parenthetic expression.
