Fractional decimal number write a comma. The whole part is written left of the decimal, fractional on the right. The purpose of the procedure of rounding is to crop the right part and bring the number to an integer value. The precision of the number when it is lowered. Round to tenths of a share means to keep the fraction one digit after the decimal point to the right. If the number has no decimal point, that is, it is integer, its up to tenths rounding is not necessary. After the comma it is written the number zero. The number 65 can be written in the form of 65.0 (sixty five point, zero - tenths).
To round non-integer number to the tenth, please note the figure for the tenth shares. It is located second to the right of the decimal point. If it is greater than four, i.e., equal to one of the digits 5, 6, 7, 8, 9, the tenth increase by one unit. The number of 56.37 after rounding equal to 56,4 (fifty-six point thirty-seven hundredths equal to approximately fifty-six whole four tenth).
If the second digit right of the decimal point has a value less than or equal to four, i.e. 1, 2, 3, 4, the tenth will not change. The number of 3.34 after rounding is equal to 3.3 (three point thirty-four hundredths approximately equal to three whole three tenth). The number 96,11 after rounding equal to 96,1 (ninety-six point eleven hundredths approximately equal to ninety-six whole one tenth).
Don't forget that rounding reduces accuracy class changing number.
Similarly, rounding numbers to any number of decimal places. The value of the last remaining figures depend on the digits that can appear after it.
