Perform the following floating-point operations assuming that both numbers are represented in a normalized (regular normalization), decimal floating-point system with a 4-digit length mantissa (i.e., 4 significant figures). Remember to write down the numbers in the appropriate format to do the operations, and to give the final result using the floating-point system described above. Use chopping. Compute the true percent relative errors when asked. a) 0.8672 + 0.6935 (compute epsilon_t) b) 5.63 +0.056879 c) 510+0.001693 (compute epsilon_t) d) 1.7059-1.7048 (compute epsilon_t) e) 63.2 times 3.159 (compute epsilon_t) f) 0.056793/0.004973
