"Jon has delivered a book which is a pleasure to read and the narrative used throughout is highly informative yet concise. The author is well respected in the F# community and F# for Technical Computing is a good example why so many people stop and listen when Jon has something to say on the subject. The book can be read cover to cover; alternatively, it can be used as an effective reference. It is one of only two books on F# which I find myself consulting regularly - an excellent resource for new or experienced F# programmers. Highly recommended."
