toricDivisorFromCycle -- Convert a codimension one toric cycle into a toric divisor

• Usage:

  degCycle(C)

• Inputs:
  • C, a toric cycle,
• Outputs:
  • d, an integer,

i1 : X = toricProjectiveSpace 2;

i2 : D = X_{0} + X_{1};

o2 : ToricCycle on X

i3 : toricDivisorFromCycle D

o3 = X  + X
      0    1

o3 : ToricDivisor on X
