calc.clear()

result = object.add(number)

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()
