Digit at ten-thousandths
                                                                                        place is greater than 5.
                          b.  Given decimal = 0.88 2 9

                                                                                     Digit at thousandths place

                            So, increase the thousandths place digit by 1 and

                              replace each digit after it with 0.

                            \ Rounded off number of 0.8829 = 0.8830


                                                                                       Digit at ten-thousandths
                                                                                                place is 5.
                          c.  Given decimal = 57.06 3 5

                                                                                     Digit at thousandths place

                            So, increase the thousandths place digit by 1 and

                              replace each digit after it with 0.

                            \ Rounded off number of 57.0635 = 57.0640
