Calculate FV Same formula as Excel FV()

	/*
	Calculate FV.
	Exact same Excel FV function

	Rate is the interest rate per period.
	Nper is the total number of payment periods in an annuity.
	Pmt is the payment made each period; it cannot change over the life of the annuity. Pmt must be entered as a negative number.
	Pv is the present value, or the lump-sum amount that a series of future payments is worth right now. If pv is omitted, it is assumed to be 0 (zero). PV must be entered as a negative number.
	Type is the number 0 or 1 and indicates when payments are due. If type is omitted, it is assumed to be 0 which represents at the end of the period. If payments are due at the beginning of the period, type should be 1.

solved transition flickering when transition to the top of 2nd page. Both panels are positioned absolute, and using translate3d to move the panel. Each panel has its own overflow setting, so it doesn't impact other panel. Padding-bottom is added to the parent panel (#panels), so it'll hide the toolbars (tested on iOS 6, may not work on iOS 7)
