SUMMARY

The discussion focuses on calculating the radix economy for complex bases, specifically Donald Knuth's Quater-Imaginary base (2i). The formula for radix economy is defined as the product of the number of digits required and the number of digits possible. For the Quater-Imaginary base, there are four digit possibilities, leading to an economy calculation of E(2i, -35+40i) = 28. The challenge arises when applying the Econ function to complex numbers, resulting in complex logarithmic outputs that complicate the understanding of number length in these bases.

The same way
digits required*number of digits possible

for Quater-Imaginary base there are 4 digit possibilities so
1223101 (base 2i)
has
E(2i,-35+40i)7*4=28
 
Thanks lurflurf, sorry about this but I don't understand how the Econ function would actually work with complex numbers. When I fill in the function I get a complex result:

log(-35+40)/log(2i) = 2.15.. -1.57..i

So basically I guess I'm asking how you find the length of a number in a complex base. With integer bases it works fine, but these complex bases seem more contrived..
