Detailed Description

Class implementing a number with an optional unit.

Constructor & Destructor Documentation

◆ NumberExpression()

NumberExpression::NumberExpression	(	const App::DocumentObject *	_owner = `0`,
		const Base::Quantity &	quantity = `Base::Quantity()`
	)

Member Function Documentation

◆ isInteger()

bool NumberExpression::isInteger ( long * v = 0 ) const

◆ negate()

void NumberExpression::negate ( )

Negate the stored value.

◆ simplify()

Expression * NumberExpression::simplify ( ) const

overridevirtual

Simplify the expression.

For NumberExpressions, we return a copy(), as it cannot be simplified any more.

Reimplemented from App::UnitExpression.
