Which Moves: the Decimal Point, or the Number?For example: when you multiply by 100 do you "move the decimal point 2 places to the right" ... or do you "move the number 2 places to the left".

Re: Which Moves: the Decimal Point, or the Number?Hi MIF; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20120110 10:47:20

Re: Which Moves: the Decimal Point, or the Number?I use "move the decimal" with percentages, but I get the odd email "we don't do it like that". The problem is that it is taught in different ways around the world. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #7 20120110 12:23:37

Re: Which Moves: the Decimal Point, or the Number?If you look thru a red password games red plastic seethru filter at the same time, you might see even less, or perhaps depending on the thinness of the cellophane, it might actually act as a passfilter. Assume the cellophane is only 4 molecules thick and red in color. It appears red when placed on a sheet of white paper. But this nonopaque planar object not only reflects, but it refracts and lets light straight thru too. The whole color filter thing is very curious, and not well explained to me, because how do you know just because you can see something thru it, that it is a filter? You can presume it is a filter, and then go from there, but what if it is something else, and we are making assumptions about what it does before we even know if the colors we see are a wave or a particle or both at the same time? Anyway, I like to move the number left and right instead of the decimal today, since it seems so cool!! igloo myrtilles fourmis #9 20120203 06:48:17
Re: Which Moves: the Decimal Point, or the Number?Both is the correct answer. #10 20120203 07:51:00

Re: Which Moves: the Decimal Point, or the Number?We move them in practice , either one depending on the representation base used, because it's easier to "cut&paste" a dot rather than all digits, but of course the point is fixed. It's like the birds with their heads when walking! #12 20120203 09:17:44
Re: Which Moves: the Decimal Point, or the Number?i see that you didn't get it.the pun was that the decimal point is decimal in both decimal and duodecimal system.

Re: Which Moves: the Decimal Point, or the Number?Oh yeah, it's just that decimal comes form deca = ten in greek. So it would make sense if we had a duodecimal system it would be called duodecimal point from duo + deca = twelve in greek. #14 20120204 07:35:58
Re: Which Moves: the Decimal Point, or the Number?that's my whole 'point',but i'm not very good at making puns as you might see.
