Radix 2 and Radix 4

Started by Appalayagari Sreedhar May 24, 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.

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.

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

I meant the logarithmic scale. In this scale the log of any number to
the base 4 is half that to the base 2.
(i.e log_4(16) = 2 = 1/2*log_2(16))
