Operations with fractional index between + and * ?
#2
Hmm, couldn't resist....
I just tried this for some numerical data without further checking, whether this all can eventually give a meaningful concept.
Anyway.
I've considered the ten fractionally indexed oprations between mul() and pow(). Base is sqrt(2), initial value x0 is 2.0 because with x0=1 the power-operation would give trivial result. The iteration-height h is 1,2 and 3. The (fractional) operation-index is k; k=0 means mul(x0,sqrt(2),h), k=1 means pow(x0,sqrt(2),h)

Here are the results:

Code:
´          h=1                h=2             h=3
´    |  2.0* b^1.0      2.0* b^2.0      2.0* b^3.0                          
  k  | 2.82842712475   4.00000000000   5.65685424949  <--- mul(2,sqrt(2),h)  , direct computation
