Put the calculator in scientific display mode (SHIFT>MODE(Setup)>FIX. You will be asked to enter the number of fixed decimal digits. Enter 2 for hundredths, and 3 for thousandths. To round to the nearest hundreds or the nearest thousands, do it by hand as follows.
For hundreds
Locate the hundred digit. Let it be h.
If the next digit (the tens digits is less than 5 replace the 10 and unit digits each by 0. Your result will look like ...h00.
If the 10s digit is 5 or above (5, 6, 7, 8, 9) you must round up by increasing the hundreds digits by 1. Your result will look like ...(h+1)00
For thousands
Let the thousand digits be t
If the hundreds digits to its right is less than 5, replace it and the digits following it by 0. Your result will look like ...t000.
If the hundreds digit is 5 or higher, increase the thousands digits by 1 and replace the hundreds, tens, and units digits by 0. You result will end with (t+1) 000
Note if (h+1) or (t+1) give you 10, put a zero at their positions and increase the digit to the left by 1.
Example. 78997 to the nearest hundreds 78997 becomes 789(9+1)0 or 78(9+1)00 or 79000
