Rounding
a Number
A method of approximating a number using a nearby
number at a given degree of accuracy.
For example, 3.14159265...
rounded to the nearest thousandth is 3.142. That is because
the third number after the decimal point is the thousandths place,
and because 3.14159265... is closer to 3.142 than 3.141.
