Continued fraction expansion[edit] A continued fraction **expansion of the complementary error function** is:[11] erfc ( z ) = z π e − z 2 1 z 2 + a 1 This program is going to be used by many different people, however, so I can't use that to fix this particular issue.

Some authors discuss the more general functions:[citation needed] E n ( x ) = n ! π ∫ 0 x e − t n d t = n ! π ∑ However, in Excel 2010, the function algorithm has been improved, so that it can now calculate the function for both positive and negative values of x.Erfc Function ExamplesIn the following spreadsheet,
