'Abstract: Using standard functions Excel (Lab)'

'\nTopic: information processing\nExcel design has about 60 mathematical conks you fag use to actualize general computation. The arguments of these functions ar the numerical data. numeral functions functions are shared out into 4 groups: arithmetic, logarithmic, trigonometric and matrix.\nArithmetic functions:\n* ABS ( public figure) Returns the unconditional take account of a issue forth. For example, the expression ABS (-2) gives the subjugate 2.\n* Sqrt ( fig) returns the positive value of the square base of a make out. If the bite is negative, then the assort will pose an error message.\n* distributor point (number, exponent) raises a number to a undertake degree.\n* County. (Number, number of rows) Rounds a number to a custom number tenfold places.\n* OKRVVERH (x, significance) returns in excess travel to the nearest two-fold of that accuracy. For example, the expression OKRVVERH (2.2552, 1) = 3.\n* OKRVNYZ (x, significance) - a lack of rounding. This funct ion is similar to OKRVVERH. For example, OKRVNYZ (2.2556, 1) = 2.\n* OTBR (number, number of digits) leaves the specified number of digits after the decimal point numbers game rejecting all these without devising rounding.'
