A systematic investment plan (SIP) is an investment vehicle offered by many mutual funds to investors, allowing them to invest small amounts periodically instead of lump sums. The frequency of investment is usually weekly, monthly or quarterly.
Excel maintains 15 figures in its numbers, but they are not always accurate; mathematically, the bottom line should be the same as the top line, in 'fp-math' the step '1 + 1/9000' leads to a rounding up as the first bit of the 14 bit tail '10111000110010' of the mantissa falling off the table when adding 1 is a '1', this up-rounding is not undone when subtracting the 1 again, since there is no ...
In Excel, the PV and FV functions take on optional fifth argument which selects from annuity-immediate or annuity-due. An annuity-due with n payments is the sum of one annuity payment now and an ordinary annuity with one payment less, and also equal, with a time shift, to an ordinary annuity.
Note the formula on the dot-matrix line above and the answer on the seven-segment line below, as well as the arrow keys allowing the entry to be reviewed and edited. This calculator program has accepted input in infix notation, and returned the answer , ¯. Here the comma is a decimal separator.
The formula above can be used for more than calculating the doubling time. If one wants to know the tripling time, for example, replace the constant 2 in the numerator with 3. As another example, if one wants to know the number of periods it takes for the initial value to rise by 50%, replace the constant 2 with 1.5.
Profitability index (PI), also known as profit investment ratio (PIR) and value investment ratio (VIR), is the ratio of payoff to investment of a proposed project.It is a useful tool for ranking projects because it allows you to quantify the amount of value created per unit of investment.
In numerical analysis, Stone's method, also known as the strongly implicit procedure or SIP, is an algorithm for solving a sparse linear system of equations. The method uses an incomplete LU decomposition , which approximates the exact LU decomposition , to get an iterative solution of the problem.
Leibniz formula for π — alternating series with very slow convergence; Wallis product — infinite product converging slowly to π/2; Viète's formula — more complicated infinite product which converges faster; Gauss–Legendre algorithm — iteration which converges quadratically to π, based on arithmetic–geometric mean
