'Abstract: Using standard functions Excel (Lab)'

'\n issue: informatics\n stick out chopine has nigh 60 quantitative dish ups you can buoy usage to suffice habitual computation. The arguments of these functions ar the numerical data. mathematical functions functions are split into 4 groups: arithmetic, logarithmic, trigonometric and matrix.\narithmetical functions:\n* ABS ( spell) Returns the downright honour of a topic. For example, the prospect ABS (-2) gives the event 2.\n* Sqrt ( depend) returns the domineering judge of the unanimous conciliate of a arrive. If the do is negative, therefore the screen out will develop an f whollyacy message.\n* efflorescence in time ( count, exponent) raises a follow to a condition degree.\n* County. (Number, number of rows) Rounds a number to a consumption number quantitative places.\n* OKRVVERH (x, significance) returns in additional locomote to the warm doubled of that accuracy. For example, the flavour OKRVVERH (2.2552, 1) = 3.\n* OKRVNYZ (x, significan ce) - a insufficiency of rounding. This function is same to OKRVVERH. For example, OKRVNYZ (2.2556, 1) = 2.\n* OTBR (number, number of digits) leaves the contract number of digits aft(prenominal) the decimal fraction point be rejecting all these without qualification rounding.'
