# ~ ROUNDING OFF NUMBERS ~ ## GET THESE RULES FOR ROUNDING OFF NUMBERS

 CASE A: In rounding off numbers, the last figure kept should be unchanged if the first figure dropped is less than 5. For example, if only one decimal is to be kept, then 6.422 becomes 6.4. CASE B: In rounding off numbers, the last figure kept should be increased by 1 if the first figure dropped is greater than 5. For example, if only two decimals are to be kept, then 6.4872 becomes 6.49. Similarly, 6.997 becomes 7.00. CASE C: In rounding off numbers, if the first figure dropped is 5, and all the figures following the five are zero or if there are no figures after the 5, then the last figure kept should be unchanged if that last figure is even. For example, if only one decimal is to be kept, then 6.6500 becomes 6.6. For example, if only two decimals are to be kept, then 7.485 becomes 7.48. CASE D: In rounding off numbers, if the first figure dropped is 5, and all the figures following the five are zero or if there are no figures after the 5, then the last figure kept should be increased by 1 if that last figure is odd. For example, if only two decimals are to be kept, then 6.755000 becomes 6.76. For example, if only two decimals are to be kept, 8.995 becomes 9.00. CASE E: In rounding off numbers, if the first figure dropped is 5, and there are any figures following the five that are not zero, then the last figure kept should be increased by 1. For example, if only one decimal is to be kept, then 6.6501 becomes 6.7. For example, if only two decimals are to be kept, then 7.4852007 becomes 7.49.
