Why Might The Life Of Pi Be A Work Of Magical Realism?

In the novel, Life of Pi, Yann Martel made the book very fascinating with many metaphors and symbolism included in the story that makes you think deeper about the context. Life Of Pi could be a work of magical realism because of it's many metaphors and his use of the word Pi or 3.14. Martel may have used this to show that 3.14 is representing something deeper. It could be 3 for how many religions he worshipped, 1 for him alone on the boat, and 4 for the number of animals on the boat with him. This ties to his theme because everyone has purpose in life and maybe Pi's purpose was to tell his great story to others.
