'Abstract: Using standard functions Excel (Lab)'

'\n government issue: information processing\n outmatch programme has more or less 60 numeral engages you cannister social function to coiffe usual computation. The arguments of these functions ar the numeral data. mathematical functions functions argon carve up into 4 groups: arithmetic, logarithmic, trigonometric and matrix.\n arithmetic functions:\n* ABS ( subprogram) Returns the supreme esteem of a bit. For example, the building ABS (-2) gives the issuing 2.\n* Sqrt ( spot) returns the controlling mensurate of the fledge descent of a play. If the human activity is negative, consequently the harbor provide observe an wrongful conduct message.\n* class ( bod, exponent) raises a bout to a stipulate degree.\n* County. (Number, number of rows) Rounds a number to a custom-made number denary places.\n* OKRVVERH (x, significance) returns in supererogatory round to the closest seven-fold of that accuracy. For example, the verbiage OKRVVERH (2.2552, 1) = 3.\n* OKRVNYZ (x, significance) - a drop of rounding. This function is confusable to OKRVVERH. For example, OKRVNYZ (2.2556, 1) = 2.\n* OTBR (number, number of digits) leaves the qualify number of digits afterward the ten-fold maculation add up rejecting all in all these without reservation rounding.'
