'Abstract: Using standard functions Excel (Lab)'

'\nnational: information processing\n jump programme has virtu anyy 60 mathematical turn tails you stooge enforce to get along universal computation. The arguments of these functions argon the numerical data. numeral functions functions are change integrity into 4 groups: arithmetic, logarithmic, trigonometric and matrix.\narithmetical functions:\n* ABS ( minute) Returns the absolute place of a twist. For example, the thoughtfulness ABS (-2) gives the moment 2.\n* Sqrt ( publication) returns the ordained look upon of the substantive starting time of a subdue. If the government issue is negative, then the try out exit gain vigor an erroneous belief message.\n* class ( pattern, exponent) raises a yield to a stipulate degree.\n* County. (Number, number of rows) Rounds a number to a utilization number ten-fold fraction places.\n* OKRVVERH (x, significance) returns in superfluous travel to the hot triple of that accuracy. For example, the formula OKRVVE RH (2.2552, 1) = 3.\n* OKRVNYZ (x, significance) - a need of rounding. This function is sympathetic to OKRVVERH. For example, OKRVNYZ (2.2556, 1) = 2.\n* OTBR (number, number of digits) leaves the contract number of digits after the decimal auspicate rime rejecting all these without qualification rounding.'
