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.
The modified internal rate of return (MIRR) is a financial measure of an investment's attractiveness. [1] [2] It is used in capital budgeting to rank alternative investments of unequal size. As the name implies, MIRR is a modification of the internal rate of return (IRR) and as such aims to resolve some problems with the IRR.
Still, depending on the assertion, the simple formula may provide a satisfactory calculation. More generally, because ECV is a simplified version of ENPV, it has the limitations of the more general approach (including omission of non-financial sources of project value, and the potential for insufficient treatment of risk).
Google engineer Emma Haruka Iwao has calculated pi to 31 trillion digits, breaking the world record.

where C is the circumference of a circle, d is the diameter, and r is the radius.More generally, = where L and w are, respectively, the perimeter and the width of any curve of constant width.
The Chudnovsky algorithm is a fast method for calculating the digits of π, based on Ramanujan's π formulae.Published by the Chudnovsky brothers in 1988, [1] it was used to calculate π to a billion decimal places.
