Is it possible to calculate the degree of a toric divisor directly from the fan of the toric variety? If so, how is this done? Or is there some alternative way to calculate the degree of these divisors?

    The set of Cartier T-divisors on a fan is exactly the set of piecewise linear integral functions on the fan. Given such a function, one can recover the divisor by finding the values of the function at the first lattice elements which are the coefficients of the irreducible divisors associated to rays ( 1- dimensional cones)2012-07-22
