Radix 2 and Radix 4 - Appalayagari Sreedhar - May 24 5:38:00 2003

Dear Friends, Can u clear my query, What exactly is the difference between the radix 2 and radix 4 and how the number of computations vary. Thanks in advance. regds,sree. Catch all the cricket action. Download Yahoo! Score tracker |

Hi Sreedhar, The radix is simply the base of the number system you want to use. Therfore, when you consider the logarithmic scale, any number in radix 4 system is half the value it has in the radix 2 system. As regards your question about the number of computations, I am not sure in what respect you have posed this question. N |

Hello To my understanding.. The decimal number system that we all use has radix 10 meaning u have 0 to 9 numbers to count on and then 10 Radix 2 will be number system with only two digits 0 and 1. so decimal number 2 will be represented as 10 and 3 as 11 and so on For radix 4 u will have numbers 0 1 2 and 3 in ur number system and there u will represent number 4 as 10 and number 5 as 11 and so on... so I think the other solution given is not correct as all values are not going to be half! 0 and 1 have same value in both number systems! Hope it helps Regards, Amit --- Appalayagari Sreedhar <> wrote: > Dear Friends, > > Can u clear my query, > > What exactly is the difference between the radix 2 > and radix 4 and how the number of computations vary. > > Thanks in advance. > > regds,sree. > > Catch all the cricket action.
