Methods

_factory.create()

The factory create method returns a calculator object.

It takes no parameters.

The method will return null if create fails, such as with bad parameters.

You can call create multiple times to create multiple calculater objects.

object.clear()

Sets the internal accumulator to zero.

calc.clear()

result = object.add(number)

Adds number to the internal accumulator. Returns the new value of the accumulator.

calc.add(2)

result = object.sub(number)

Subtracts number from the internal accumulator. Returns the new value of the accumulator.

calc.sub(2)

result = object.div(number)

Divides the value of the internal accumulator by number. Returns the new value of the accumulator. If divided by 0, accumulator will be set to infinity.

calc.div(2)

result = object.value()

Returns the current value of the internal accumulator.

var result = calc.value();
