Actually... that's not the EXACT number. It looks to be an irrational number. And because it's most likely an irrational number, the EXACT number can't be written as a decimal. You can only get an approximation accurate to what ever decimal you need it to be. The calculator on my computer will only go to 16 sig figs. So to 16 figures it's 1.04719755858073. If you need it more accurate than that, you'll have to pull out a calculus book and brush up on your Taylor Series polynomials.
