However, the first form keeps better numerical accuracy for large values of x, because squares of differences between x and x leads to less round-off than the differences between the much larger numbers Σ(x 2) and (Σx) 2. The built-in Excel function STDEVP, however, uses the less accurate formulation because it is faster computationally. [5]
A forward exchange contract is identified as an agreement that is made between two parties with an intention of exchanging two different currencies at a specific time in the future. In this situation, a business makes an agreement to buy a given quantity of foreign currency in the future with a prearranged fixed exchange rate (Walmsley, 2000).

Strike price – the asset price at which the investor can exercise an option.
The conventions of this class calculate the number of days between two dates (e.g., between Date1 and Date2) as the Julian day difference. This is the function Days(StartDate, EndDate). The conventions are distinguished primarily by the amount of the CouponRate they assign to each day of the accrual period.
In finance, a foreign exchange swap, forex swap, or FX swap is a simultaneous purchase and sale of identical amounts of one currency for another with two different value dates (normally spot to forward) [1] and may use foreign exchange derivatives. An FX swap allows sums of a certain currency to be used to fund charges designated in another ...
Besides differences in the schema, there are several other differences between the earlier Office XML schema formats and Office Open XML. Whereas the data in Office Open XML documents is stored in multiple parts and compressed in a ZIP file conforming to the Open Packaging Conventions, Microsoft Office XML formats are stored as plain single monolithic XML files (making them quite large ...
