Title: Complete waste of my time
Review: I don't know about you, but doing complex numbers in T-SQL doesn't interest me in the least, especially when the computations are inaccurate and incredibly slow. The whole book is a waste of time. We get to learn how Itzik's code formatting style differs from Tom's (who cares -- who the heck is either of these guys?) We get to learn how neat it is to run into someone with the same first name. And we get to hear about Itzik's martial arts master (really interesting stuff... not). I am returning this one for a refund.
