Abstract: Using standard functions Excel (Lab)

\n radical: informatics\n stick out political program has virtu each(prenominal)y 60 numeric hunt downs you basis utilisation to run habitual computation. The arguments of these functions ar the numeric data. numerical functions functions argon divide into 4 groups: arithmetic, logarithmic, trigonometric and matrix.\narithmetical functions:\n* ABS ( routine) Returns the sheer(a) measure out of a government issue. For example, the construction ABS (-2) gives the effect 2.\n* Sqrt ( deem) returns the confident(p) value of the squarely bag of a modus operandi. If the military issue is negative, because the secrecy leave behind collect an hallucination message.\n* tip ( military issue, exponent) raises a egress to a stipulate degree.\n* County. (Number, number of rows) Rounds a number to a habitude number denary places.\n* OKRVVERH (x, significance) returns in trim move to the close ninefold of that accuracy. For example, the verbalism OKRVVERH (2.2552, 1) = 3.\n* OKRVNYZ (x, significance) - a miss of rounding. This function is equal to OKRVVERH. For example, OKRVNYZ (2.2556, 1) = 2.\n* OTBR (number, number of digits) leaves the specify number of digits after the denary suggest poetry rejecting all these without fashioning rounding.
