→‎Repeating the "why"?
Line 51:
: I can remove the "I" from my task implementation when that ceases to be relevant. But you asked for the reason that the task cannot be implemented in a certain fashion and my lack of understanding is the reason. So, for now, "I" stays... Note that I am not using BCD at all here -- the closest I come to that is the initial and final representations of the numbers, but that's ASCII, not BCD.
 
: Also, analyzing your sequence: the exponents 63, 54, 45, 36, ... each differ by 9, and correspond to the9 multipliers* (7, 6, 5, 4). So if 63 corresponds to the -8 value in your sequence, then the exponent of 0 corresponds to -1, and the exponent of -9 corresponds to 0. I suspect this is an off-by-one error? Wouldn't it make more sense for 63 to correspond to -7? Or, better yet, make 63 correspond to 7, and ask for the values from 7 through -21 (or whatever -- since these values are bulky perhaps it would be better for the task page to ask for fewer, well chosen values? --[[User:Rdm|Rdm]] 12:22, 30 October 2011 (UTC)
