Question

There are several methods for rounding, including round toward 0, round toward positive infinity, round toward negative infinity, and round to nearest. In this assignment, you are supposed to fully explain these methods and provide at least two examples

Answer 1

A) 300.001 = 300

6.75 = 6

B) + 36.5 = +37

+54.6 = +55

C) -45.6 = - 46

-25.5 = -26

D) 2888 = 2890 ( nearest ten)

2888 = 2900 ( nearest hundreds)

2888 = 3000 ( nearest thousands)

Explanation:

Round toward 0

Rounding towards zero is a simple rounding mode. All digits beyond the number required are dropped. Rounding towards zero results in a number whose magnitude is always less than or equal to the more precise original value.

Examples are:

300.001 = 300

6.75 = 6

Round toward positive infinity

This means the result of the rounding is never smaller than the argument. Examples are:

+ 36.5 = +37

+54.6 = +55

Round toward negative means the result of the rounding is never larger than the argument.

Examples are

-45.6 = - 46

-25.5 = -26

Round to nearest means the result of rounding is sometimes larger, sometimes smaller than (and sometimes equal to) the argument

It can be to the nearest ten, hundreds, thousands or millions etc

2888 = 2890 ( nearest ten)

2888 = 2900 ( nearest hundreds)

2888 = 3000 ( nearest thousands)
