toAffineChart(ZZ,List) -- coordinates of a point in the projective space in an affine chart

Synopsis

Description

i1 : toAffineChart(2,{1,2,3,4,5,6}) 

      1  2  4  5
o1 = {-, -, -, -, 2}
      3  3  3  3

o1 : List
i2 : toAffineChart(2,{1,2,0,4,5,6}) 

o2 = infinity

o2 : InfiniteNumber

Caveat

Returns infinity if the i-th coordinate of x is zero.
